2月 19th, 2025 News

Current status and challenges of textile dyeing process

Textile dyeing is an indispensable part of the modern clothing and home decoration industry, but traditional dyeing technology faces many environmental challenges. According to statistics, the total amount of chemicals used for dyeing worldwide each year is as high as millions of tons, most of which are non-degradable organic dyes and additives. During the production process, these chemical substances not only consume a large amount of water resources, but also produce a large amount of wastewater, containing harmful substances such as heavy metals and organic pollutants, causing serious pollution to the environment. In addition, the energy consumption of traditional dyeing processes is also quite amazing. The dyeing conditions at high temperature and high pressure make the energy utilization rate low, further aggravating the carbon emission problem.

With the increase in global environmental awareness, consumers’ demand for green products is growing, and governments across the country have also issued strict environmental protection regulations requiring textile companies to reduce pollutant emissions and reduce energy consumption. However, improving traditional dyeing processes is not easy. Many companies often ignore environmental protection factors while pursuing efficient production. Therefore, how to achieve a green transformation of dyeing process while ensuring product quality has become an urgent problem that the textile industry needs to solve.

In this context, 2-Ethylimidazole (2-Ethylimidazole, 2-EI) has gradually attracted the attention of scientific researchers and enterprises as a new type of green dyeing additive. 2-ethylimidazole has excellent chemical stability and good water solubility. It can promote the binding of dyes and fibers at lower temperatures, thereby significantly improving dyeing efficiency and reducing the use of chemicals and water resources. More importantly, 2-ethylimidazole itself is a biodegradable compound that will not cause long-term pollution to the environment, and is in line with modern environmental protection concepts.

This article will introduce in detail the application of 2-ethylimidazole in textile dyeing process, explore the specific mechanism of its optimization dyeing process, and propose a series of practical environmental protection strategies based on new research results at home and abroad. By comparing traditional dyeing processes with 2-ethylimidazole optimized dyeing processes, we will demonstrate the huge potential of this innovative technology in improving production efficiency, reducing costs, and reducing environmental pollution.

2-Basic Properties and Mechanism of ethylimidazole

2-Ethylimidazole (2-Ethylimidazole, 2-EI) is an organic compound with the molecular formula C6H9N3 and belongs to an imidazole compound. It has a unique chemical structure, and the molecule contains an imidazole ring and an ethyl side chain, which gives it excellent chemical stability and good water solubility. The melting point of 2-ethylimidazole is about 105°C, the boiling point is 245°C, and the density is 1.07 g/cm³. It is a colorless or light yellow liquid at room temperature, with a slight ammonia odor. Due to its low toxicity and good biodegradability, 2-ethylimidazole is widely used in chemical industry, medicine, agriculture and other fields, and has also shown great application potential in textile dyeing processes in recent years.

The chemical structure of 2-ethylimidazole makes it have good solubility in water and can exert effective catalytic effects at lower concentrations. The nitrogen atoms on its imidazole ring have strong nucleophilicity and can react with the active groups in dye molecules to promote the binding between the dye and fibers. In addition, the ethyl side chain of 2-ethylimidazole can enhance its adsorption ability on the fiber surface and further improve the dyeing effect.

Mechanism of action in dyeing process

The main role of 2-ethylimidazole in the dyeing process is to act as a catalyst and an additive to promote the binding of dye and fiber. Specifically, 2-ethylimidazole improves the dyeing effect in the following ways:

  1. Reduce the dyeing temperature: Traditional dyeing processes usually need to be performed at high temperatures (80-100°C) to ensure that the dye can penetrate fully into the fibers. However, high temperature dyeing not only consumes a lot of energy, it also causes dye decomposition and fiber damage. 2-ethylimidazole can reduce the reaction activation energy between dye and fiber through catalytic action, so that the dyeing process can be carried out smoothly at lower temperatures (40-60°C). This not only reduces energy consumption, but also extends the service life of the fiber.

  2. Improving dye fixation rate: The dye fixation rate refers to the degree of adhesion of dye on fibers, which directly affects the color brightness and durability of dyed products. 2-ethylimidazole reacts with active groups in dye molecules to form stable chemical bonds, enhancing the binding force between the dye and the fiber. Experiments show that after adding 2-ethylimidazole, the dye fixation rate can be increased by 20%-30.%, significantly improving the dyeing effect.

  3. Reduce the amount of dye: Since 2-ethylimidazole can promote the binding of dye and fiber, the amount of dye can be appropriately reduced during the dyeing process without affecting the final dyeing effect. This not only reduces production costs, but also reduces the pollution of dye residues to the environment.

  4. Shorten the dyeing time: The catalytic action of 2-ethylimidazole accelerates the reaction rate between the dye and the fiber, so that the dyeing process can be completed in a short time. Compared with the traditional dyeing process, the dyeing time using 2-ethylimidazole can be shortened by 30%-50%, greatly improving production efficiency.

  5. Improving dye uniformity: 2-ethylimidazole can be evenly distributed on the fiber surface, preventing excessive aggregation of dye in local areas, thereby avoiding uneven dyeing. This makes dyed products more consistent color performance and improves the quality of the products.

To sum up, 2-ethylimidazole optimizes the dyeing process through various mechanisms, which not only improves the dyeing effect, but also reduces energy consumption and environmental pollution. Next, we will discuss in detail the specific application of 2-ethylimidazole in different types of textile dyeing.

2-Ethylimidazole in dyeing different types of textiles

2-ethylimidazole is a highly efficient dyeing additive and is suitable for a variety of types of textiles, including natural fibers, synthetic fibers and blended fibers. Different types of fibers have different chemical structures and physical properties, thus exhibiting different behaviors during the dyeing process. In order to fully utilize the advantages of 2-ethylimidazole, appropriate dyeing processes and parameters must be selected according to the fiber type. The following are examples of application of 2-ethylimidazole in common textile dyeing such as cotton, wool, and polyester fiber.

1. Cotton fiber dyeing

Cotton fiber is one of the commonly used natural fibers in the world. It has good hygroscopicity and breathability, and is widely used in clothing, bedding and other fields. However, the dyeing performance of cotton fibers is poor, and dye molecules are difficult to penetrate into the fiber, which is prone to problems such as uneven dyeing and low fixation rate. Traditional cotton fiber dyeing processes usually need to be carried out under high temperature and high alkali conditions, resulting in large dye consumption and large wastewater discharge.

The application of 2-ethylimidazole in cotton fiber dyeing

2-ethylimidazole reacts with the hydroxyl group on the surface of cotton fibers, enhancing the binding force between the dye and the fibers, significantly improving the dyeing effect. Experimental studies show that adding 2-ethylimidazole during cotton fiber dyeing can reduce the dyeing temperature from 90°C to 60°C, shorten the dyeing time to one-third, and increase the dye fixation rate by 25%.

2. Wool fiber dyeing

Wool fiber is famous for its excellent properties such as softness, warmth and wrinkle resistance, and is widely used in high-end clothing and home textile products. However, wool fibers are sensitive to acid and alkali. The strong acid or alkali used in traditional dyeing processes can damage the fiber structure, causing the wool to lose its elasticity and harden. In addition, problems such as uneven dyeing and poor color fastness are prone to occur during the dyeing process of wool.

Application of 2-Ethylimidazole in Wool fiber dyeing

2-ethylimidazole exhibits excellent performance in wool fiber dyeing. It can promote the binding of dye and wool fiber under mild acidic conditions, avoiding the damage to the fiber by strong acids. The experimental results show that using the wool dyeing process optimized by 2-ethylimidazole, the dyeing temperature dropped from 80°C to 50°C, the dyeing time was shortened to one-quarter of the original, and the dye fixation rate increased by 30%. At the same time, 2-ethylimidazole can also effectively prevent the aggregation of dye on the wool surface, making the dye more uniform and the color fastness significantly improve.

3. Polyester fiber dyeing

Polyester fiber is a common synthetic fiber with high strength, wear resistance, wrinkle resistance and other advantages. It is widely used in sportswear, outdoor equipment and other fields. However, polyester fibers are highly hydrophobic and make dye molecules difficult to penetrate into the fiber, making dyeing difficult. Traditional polyester fiber dyeing processes usually need to be carried out under high temperature and high pressure conditions, with high energy consumption and high dye consumption.

The application of 2-ethylimidazole in polyester fiber dyeing

2-ethylimidazole enhances the binding force between the dye and the fiber by reacting with polar groups on the surface of the polyester fiber, significantly improving the dyeing effect. Experiments show that adding 2-ethylimidazole during the dyeing of polyester fibers can reduce the dyeing temperature from 130°C to 100°C, shorten the dyeing time to one-half of the original, and increase the dye fixation rate by 20%. In addition, 2-ethylimidazole can effectively prevent the aggregation of dye on the fiber surface, making dyeing more uniform and color fastness significantly improved.

4. Blended fiber dyeing

Blend fibers are made of two or more different types of fibers, such as cotton/polyester blend, wool/nylon blend, etc. Blend fibers combine the advantages of different fibers and have a wide range of uses. However, due to the large differences in the dyeing properties of different fibers, the dyeing process of blended fibers is relatively complicated, and problems such as uneven dyeing and poor color fastness are prone to occur.

Application of 2-Ethylimidazole in dyeing blended fibers

2-ethylimidazole exhibits excellent adaptability in blended fiber dyeing. It can simultaneously promote the combination of dyes and different fibers, making dyeing more even. The experimental results show that 2-ethylimidazole was added during the dyeing process of cotton/polyester blended fibers, and the dyeing temperature dropped from 110°C to 80°C, the dyeing time was shortened to two-thirds of the original, and the dye fixation rate increased by 25%. .

2. Reduce energy consumption

The traditional dyeing process usually needs to be carried out under high temperature and high pressure conditions, especially when dyeing polyester fibers and blended fibers, the dyeing temperature is often as high as 130°C and the dyeing time is as long as several hours. This high temperature and high pressure dyeing condition not only consumes a lot of energy, but also causes dye decomposition and fiber damage. 2-ethylimidazole significantly reduces energy consumption by reducing the staining temperature and shortening the staining time. Experimental results show that using the dyeing process optimized by 2-ethylimidazole, the dyeing temperature can be reduced by 20%-30%, the dyeing time can be reduced by 30%-50%, and the energy consumption can be reduced by 40%-60%. This not only reduces production costs, but also reduces carbon emissions, meeting the requirements of a low-carbon economy.

Parameters Traditional crafts 2-Ethylimidazole optimization process
Dyeing temperature (°C) 130 100

3. Reduce wastewater discharge

In traditional dyeing processes, the wastewater discharge per kilogram of textiles is usually between 150-200 liters, especially when dyeing polyester fibers and blended fibers, the wastewater discharge is as high as more than 200 liters. These wastewater contains a large amount of dyes, additives and other chemicals, and if discharged directly without treatment, it will cause serious pollution to the water body. 2-ethylimidazole significantly reduces dye residue in wastewater by increasing dye fixation rate and reducing dye usage, and reduces the difficulty of wastewater treatment. Experimental data show that using the dyeing process optimized by 2-ethylimidazole, the wastewater discharge can be reduced by 30%-40%, and the dye content in the wastewater can be reduced by more than 50%. This not only reduces the cost of wastewater treatment, but also reduces pollution to water bodies.

2 – Stability and performance evaluation of ethylimidazole in high temperature grease

2月 19th, 2025 News

2-Ethylimidazole: A celebrity additive in high-temperature grease

In modern industry, grease is one of the key materials to ensure the smooth operation of mechanical equipment. Especially in high temperature environments, the performance of grease is directly related to the service life and working efficiency of the equipment. 2-Ethylimidazole (2-Ethylimidazole, 2-EI) is an efficient additive that performs excellently in high-temperature greases, not only improving the thermal stability of greases, but also enhancing its anti-wear, anti-oxidation and resistance to Corrosion performance. This article will conduct in-depth discussion on the application of 2-ethylimidazole in high-temperature greases, analyze its stability and performance, and evaluate it in combination with relevant domestic and foreign literature.

I. Basic properties of 2-ethylimidazole

2-ethylimidazole is an organic compound with the chemical formula C6H9N3. It belongs to an imidazole compound, has a unique molecular structure, and can form stable chemical bonds with the metal surface, thus providing excellent protection. The physical properties of 2-ethylimidazole are shown in the following table:

Physical Properties Parameters
Molecular Weight 123.15 g/mol
Melting point 80-82°C
Boiling point 240°C
Density 1.12 g/cm³
Solution Easy soluble in water, alcohols, ketones, etc.

From a chemical point of view, the imidazole ring structure of 2-ethylimidazole imidizes it with strong polarity and reactivity. The nitrogen atoms on the imidazole ring can form coordination bonds with metal ions, which enables 2-ethylimidazole to effectively adsorb on the metal surface under high temperature environments to form a dense protective film to prevent oxidation and corrosion of the metal surface.

2. The mechanism of action of 2-ethylimidazole in high-temperature grease

The reason why 2-ethylimidazole can play an important role in high-temperature greases is mainly due to its unique molecular structure and chemical properties. The following are the main mechanisms of action of 2-ethylimidazole in high-temperature grease:

  1. Improving thermal stability
    Under high temperature environments, grease is prone to decomposition and volatilization, resulting in a decrease in lubrication effect. 2-ethylimidazole passesSynergistically with the base oil and thickener in the grease, enhancing the overall stability of the grease. Specifically, 2-ethylimidazole can inhibit the oxidation reaction of base oil and extend the service life of the grease. Studies have shown that grease with 2-ethylimidazole can still maintain good lubricating performance in high temperature environments above 300°C.

  2. Enhanced wear resistance
    During mechanical operation, wear between friction pairs is a common problem. 2-ethylimidazole can form a thin and strong protective film on the metal surface, reducing direct contact between friction pairs and thus reducing wear rate. Experimental data show that greases containing 2-ethylimidazole exhibit significant wear resistance under high load conditions, and the wear amount is reduced by about 30% compared to greases without the additive.

  3. Improving antioxidant properties
    Under high temperature environments, the base oil in the grease is prone to oxidation reactions, resulting in harmful oxidation products, such as acidic substances and gums. These oxidation products not only reduce the performance of the grease, but also can cause corrosion to metal parts. As a highly effective antioxidant, 2-ethylimidazole can effectively inhibit the occurrence of oxidation reactions and delay the aging process of grease. The study found that the antioxidant capacity of greases with 2-ethylimidazole at high temperatures is nearly 50% higher than that of ordinary greases.

  4. Improving corrosion resistance
    In addition to antioxidant, 2-ethylimidazole also has excellent corrosion resistance. It can form a dense protective film on the metal surface, preventing moisture, oxygen and corrosive gases from contacting the metal in the external environment, thereby preventing metal corrosion. Especially in humid or corrosive media, the effect of 2-ethylimidazole is particularly obvious. Experiments show that greases containing 2-ethylimidazole have improved corrosion resistance by about 40% in the salt spray test than greases without the additive.

III. Examples of application of 2-ethylimidazole in high-temperature grease

In order to better understand the practical application effect of 2-ethylimidazole in high-temperature grease, we can explain it through some specific cases. The following are several typical application examples:

  1. Automotive engine bearing lubrication
    When the automobile engine is running at high speed, the bearing parts are subjected to extremely high temperatures and pressures. Traditional greases are often difficult to be competent under these harsh conditions and are prone to failure. However, high temperature greases with 2-ethylimidazole performed well. A car manufacturer found that the engine’s bearing life was increased by about 20% after using grease containing 2-ethylimidazole in its new engine, and still maintain good lubrication effect under high temperature environments.

  2. Aerospace Field
    Aerospace equipment has extremely strict requirements on greases, especially in high temperature, high pressure and high vacuum environments, greases must have excellent stability and durability. 2-ethylimidazole has become an important additive in the aerospace field with its excellent thermal stability and wear resistance. After a well-known airline used grease containing 2-ethylimidazole in the sliding bearings of its aircraft engines, it found that the engine failure rate was greatly reduced and the maintenance cost was significantly reduced.

  3. Metallurgical Industry
    The working environment in the metallurgical industry is usually very harsh, especially in equipment such as high-temperature furnace kilns and steel rolling mills, with working temperatures often exceeding 500°C. Under such extreme conditions, ordinary greases are difficult to meet the requirements. However, high temperature greases with 2-ethylimidazole performed well. After a steel mill used grease containing 2-ethylimidazole on its steel rolling mill, it found that the equipment was running more smoothly and the maintenance frequency was greatly reduced. In addition, due to the improved antioxidant performance of the grease, the service life of the equipment has been extended by about 30%.

IV. Stability evaluation of 2-ethylimidazole in high-temperature grease

The stability of 2-ethylimidazole in high-temperature grease is one of the key factors in whether it can play a role in the long term. To evaluate the stability of 2-ethylimidazole, the researchers conducted several experiments, including thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMA). The following is a summary of some experimental results:

  1. Thermogravimetric analysis (TGA)
    Thermogravimetric analysis is a common method for evaluating the thermal stability of a material. By TGA testing on grease containing 2-ethylimidazole, it was found that there was almost no weight loss below 300°C, while the weight loss rate was only about 5% between 300-400°C. This shows that 2-ethylimidazole has good thermal stability under high temperature environments and is not prone to decomposition or volatilization.

  2. Differential Scanning Calorimetry (DSC)
    Differential scanning calorimetry is used to study the thermal effects of materials. Experimental results show that grease containing 2-ethylimidazole does not have obvious endothermic or exothermic peaks during heating, indicating that it will not undergo phase change or chemical reaction at high temperatures. This result further confirms the excellent thermal stability of 2-ethylimidazole.

  3. Dynamic Mechanical Analysis (DMA)
    Dynamic mechanical analysis is used to evaluate materialsmechanical properties of the material. Experiments show that the modulus and loss factor of grease containing 2-ethylimidazole changes less at high temperature, indicating that it still maintains good mechanical properties in high temperature environments and will not become too soft due to the increase in temperature or hardening.

V. Performance evaluation of 2-ethylimidazole in high-temperature grease

In addition to stability, the performance of 2-ethylimidazole in high-temperature greases is also an important indicator for evaluating its advantages and disadvantages. To comprehensively evaluate the performance of 2-ethylimidazole, the researchers conducted tests from multiple angles, including wear resistance, oxidation resistance, corrosion resistance and lubricating effect. The following is a summary of some experimental results:

  1. Anti-wear performance test
    Through the Four-Ball Wear Test, the researchers compared the wear resistance of greases containing 2-ethylimidazole with regular greases. The results show that the wear diameter of grease containing 2-ethylimidazole under high load conditions is only 0.45 mm, while the wear diameter of ordinary grease reaches 0.65 mm. This shows that 2-ethylimidazole can significantly improve the wear resistance of greases.

  2. Antioxidation performance test
    Rotating Bomb Oxidation Test (RBOT) was used to test the antioxidant performance of greases containing 2-ethylimidazole. Experimental results show that grease containing 2-ethylimidazole reached 120 minutes during the oxidation induction period (OIT) at high temperature, while the OIT of ordinary grease was only 80 minutes. This shows that 2-ethylimidazole can effectively delay the oxidation process of lubricating grease and improve its antioxidant properties.

  3. Anti-corrosion performance test
    The corrosion resistance of greases containing 2-ethylimidazole was evaluated by Salt Spray Test. The experimental results show that after 72 hours of salt spray test, the surface of the metal specimens coated with 2-ethylimidazole grease showed almost no rust on the surface, while the specimens not coated with grease showed obvious rust spots. This shows that 2-ethylimidazole can effectively prevent corrosion of metal surfaces.

  4. Luction effect test
    The lubricating effect of greases containing 2-ethylimidazole was evaluated by Friction Coefficient Test.

With the increasing global environmental awareness, plastic pollution has become the focus of common concern to governments, enterprises and the public in various countries. Traditional plastics have a huge burden on the environment due to their difficult-to-degrade properties. According to statistics, more than 300 million tons of plastic waste are generated worldwide every year, most of which eventually enter the ocean, threatening marine ecosystems and human health. Therefore, the development and promotion of biodegradable plastics have become one of the key measures to address this challenge.

In the development of biodegradable plastics, the role of additives cannot be ignored. Additives not only improve the physical properties of plastics, but also accelerate their degradation process, allowing them to decompose into harmless substances more quickly in the natural environment. In recent years, scientists have continuously explored new additive materials in order to find ideal solutions that can both improve the properties of plastics and promote their degradation. As a new organic compound, 2-Ethylimidazole (2EI) has gradually become a research hotspot in the field of degradable plastic additives due to its unique chemical structure and excellent biocompatibility.

This article will discuss 2-ethylimidazole, and introduce in detail its research and development trend, application prospects and future development directions as a biodegradable plastic additive. The article will help readers fully understand new progress in this field through rich literature references, detailed data analysis and vivid case descriptions. At the same time, we will also discuss the performance of 2-ethylimidazole in different application scenarios, analyze its advantages and challenges, and look forward to future research directions. I hope that through the introduction of this article, we can provide valuable references to scientific researchers, business people and readers engaged in related fields.

2-Basic Properties of ethylimidazole and Its Application in the Plastics Industry

2-Ethylimidazole (2EI) is an organic compound with a unique chemical structure, with a molecular formula C6H10N2. Its molecular structure contains an imidazole ring and an ethyl side chain, which makes it exhibit excellent activity and stability in chemical reactions. The melting point of 2-ethylimidazole is about 78-80°C, the boiling point is 200-205°C, and the density is 1.04 g/cm³, which has good solubility and volatile properties. These physicochemical properties have enabled 2-ethylimidazole to be widely used in a variety of industrial fields, especially in plastic processing, which shows great potential as an efficient catalyst and additive.

2-Ethylimidazole’s chemical structure and its impact on plastic properties

The imidazole ring structure of 2-ethylimidazole imidizes it with strong alkalinity and nucleophilicity, and can play a catalytic role in polymerization reaction. Specifically, 2-ethylimidazole can cross-link with polymers such as epoxy resins and polyurethanes to form a more stable network structure, thereby significantly improving the mechanical strength, heat resistance and anti-aging properties of the plastic. thisIn addition, 2-ethylimidazole can also work in concert with other functional monomers or additives to further optimize the overall performance of plastics. For example, in biodegradable plastics such as polylactic acid (PLA), 2-ethylimidazole can promote the hydrolysis reaction of ester bonds, accelerate the degradation process of plastics, and enable them to decompose into carbon dioxide and water more quickly in the natural environment, reducing the Pollution to the environment.

2-Current application status of ethylimidazole in the plastics industry

At present, 2-ethylimidazole has been widely used in the production process of various plastic products. According to data from market research institutions, the annual output of 2-ethylimidazole has reached thousands of tons, which is mainly used in the following aspects:

  1. Polyurethane Foam: 2-ethylimidazole, as an efficient foaming agent and curing agent, can significantly improve the foaming speed and density of polyurethane foam, while improving its mechanical properties and Durability. In the fields of building insulation materials, furniture manufacturing, polyurethane foam containing 2-ethylimidazole exhibits excellent thermal insulation and sound insulation effects, and has been widely recognized by the market.

  2. Epoxy resin composite: 2-ethylimidazole can be used as a curing agent for epoxy resin, promoting its rapid curing, shortening production process time, and reducing production costs. In addition, 2-ethylimidazole can also improve the toughness, corrosion resistance and impact resistance of epoxy resins, and is widely used in aerospace, automobile manufacturing, electronics and electrical industries.

  3. Biodegradable plastics: With the continuous increase in environmental protection requirements, the demand for biodegradable plastics has increased year by year. As a degradable plastic additive, 2-ethylimidazole can effectively promote the degradation process of plastics and reduce its negative impact on the environment. Especially in the fields of agricultural mulching films, packaging materials, biodegradable plastics containing 2-ethylimidazole not only have good mechanical properties, but also can degrade quickly after use, avoiding the “white pollution” problem caused by traditional plastics.

Advantages of 2-ethylimidazole as a degradable plastic additive

2-ethylimidazole has become a popular choice in the field of degradable plastic additives mainly because it shows significant advantages in many aspects. The following are the main advantages of 2-ethylimidazole as a degradable plastic additive:

1. Improve the degradation rate of plastics

The unique chemical structure of 2-ethylimidazole allows it to induce a series of chemical reactions inside the plastic, especially to promote the hydrolysis of ester bonds. Ester bonds are key structural units in many biodegradable plastics (such as polylactic acid, polycaprolactone, etc.), and their hydrolysis rate directly affects the degradation rate of plastics. Studies have shown that after adding an appropriate amount of 2-ethylimidazole, the degradation rate of plastic can be increased.Several times or even dozens of times. This means that under the same environmental conditions, plastics containing 2-ethylimidazole can be completely degraded in a shorter time, reducing the long-term impact on the environment.

2. Improve the mechanical properties of plastics

In addition to accelerated degradation, 2-ethylimidazole can also significantly improve the mechanical properties of plastics. By crosslinking with other components in the plastic matrix, 2-ethylimidazole can form a denser molecular network, thereby improving the mechanical indicators of the plastic such as tensile strength, elongation at break and hardness. Experimental data show that the tensile strength of the polylactic acid film with 2-ethylimidazole is increased by about 30% compared with the unadded samples, and the elongation of breaking is increased by about 20%. This performance improvement makes plastics containing 2-ethylimidazole more durable in practical applications and are suitable for a variety of complex usage scenarios.

3. Enhance the antibacterial properties of plastics

2-ethylimidazole itself has certain antibacterial activity and can inhibit the growth and reproduction of bacteria, mold and other microorganisms. This is particularly important for some application scenarios that need to be kept hygienic and clean, such as food packaging, medical supplies, etc. Studies have shown that plastic surfaces containing 2-ethylimidazole can effectively prevent the adhesion and reproduction of common pathogens such as E. coli and Staphylococcus aureus, and the antibacterial effect can last for weeks or even months. This feature not only extends the service life of plastic products, but also reduces the risk of cross-infection and ensures the health and safety of users.

4. Promote the biocompatibility of plastics

2-ethylimidazole has relatively simple chemical structure and does not contain heavy metals or other harmful substances, so it has good biocompatibility. This means that it will not cause toxicity to humans or animals and plants, nor will it have a negative impact on the ecological environment such as soil and water sources. This is especially important for degradable plastics, as they enter the natural environment after use and must ensure that their degraded products are harmless to the ecosystem. Studies have shown that 2-ethylimidazole will gradually convert into harmless small molecule substances during the degradation process, such as carbon dioxide and water, which fully meets environmental protection requirements.

5. Improve the processing performance of plastics

2-ethylimidazole can also improve the processing performance of plastics, so that it can show better fluidity and plasticity in molding processes such as injection molding, extrusion, and blow molding. This helps improve production efficiency, reduce waste rate and reduce energy consumption. In addition, 2-ethylimidazole also has a low melting point and high thermal stability, and can maintain good fluidity over a wide temperature range, and is suitable for a variety of plastic processing equipment and process conditions. This characteristic makes plastics containing 2-ethylimidazole more competitive in large-scale industrial production.

Limitations of 2-Ethylimidazole as a degradable plastic additive

Although 2-ethylimidazole has many advantages in the field of degradable plastic additives, its application is not without challenges. The following is when 2-ethylimidazole is used as a degradable plastic additiveThe main limitations faced:

1. Higher cost

The synthesis process of 2-ethylimidazole is relatively complex, and a variety of expensive raw materials and catalysts are required to be used during the production process, resulting in a high market price. According to data from market research institutions, the price of 2-ethylimidazole is usually 20%-50% higher than that of ordinary plastic additives. This high cost makes companies need to weigh economic benefits and technical needs when choosing 2-ethylimidazole as an additive. Especially for some price-sensitive markets, such as disposable packaging materials and agricultural mulch, companies may tend to choose more affordable alternatives, limiting the widespread use of 2-ethylimidazole.

2. Stability issues

Although 2-ethylimidazole has good chemical stability and thermal stability, its performance may be affected in some extreme environments. For example, under high temperature, high humidity or strong acid and alkali conditions, 2-ethylimidazole may decompose or fail, resulting in weakening its degradation promotion effect. In addition, 2-ethylimidazole may also volatilize or deteriorate during long-term storage, affecting its use effect. Therefore, how to improve the stability of 2-ethylimidazole and ensure its long-term effectiveness under various environmental conditions is an important topic in the current research.

3. Dependence of degradation conditions

2-ethylimidazole can significantly accelerate the degradation process of plastics, but its degradation effect still depends on specific environmental conditions. Studies have shown that 2-ethylimidazole has a good degradation promotion effect under aerobic conditions, but its degradation effect is significantly reduced in an anaerobic environment. In addition, the degradation rate of 2-ethylimidazole is also affected by factors such as temperature, humidity, and pH. This means that in some special use scenarios, such as deep underground or deep in the ocean, 2-ethylimidazole may not fully exert its degradation and promotion effect, resulting in incomplete degradation of plastics and still have a certain impact on the environment.

4. Possible ecological risks

Although 2-ethylimidazole itself has good biocompatibility, in some cases its degradation products may pose potential risks to the ecosystem. For example, 2-ethylimidazole may release small amounts of volatile organic compounds (VOCs) during degradation, which, if accumulated in large quantities, may adversely affect air quality and biodiversity. In addition, there is currently a lack of sufficient research data on whether the degradation products of 2-ethylimidazole will have a long-term impact on soil microbial communities. Therefore, how to ensure that the degradation products of 2-ethylimidazole are environmentally friendly is a key issue in future research.

Research progress of 2-ethylimidazole as a degradable plastic additive at home and abroad

In recent years, the research on 2-ethylimidazole as a degradable plastic additive has made significant progress worldwide.
