Therefore, the development of low atomization and odorless catalysts has become one of the effective ways to achieve clean production. Low atomization odorless catalyst refers to a new type of catalyst that can significantly reduce or eliminate the emission of volatile organic compounds (VOCs) and other harmful gases during the catalysis process, while maintaining efficient catalytic performance.

Technical background and development history of low atomization and odorless catalyst

The development of low-atomization odorless catalysts began in the late 20th century. With the increasing attention to environmental pollution issues, the volatile organic compounds (VOCs) and other harmful gases produced by traditional catalysts during use have become urgently needed to be solved. The problem. Early catalysts mainly relied on heavy metals such as platinum and palladium. Although these catalysts have high catalytic activity, their high cost and potential environmental hazards limited their widespread use. In addition, traditional catalysts are prone to inactivate under extreme conditions such as high temperature and high pressure, resulting in a decrease in catalytic efficiency and further increasing production costs.

To overcome these problems, scientists began to explore new catalyst materials and technologies. In the early 1990s, the rise of nanotechnology brought new opportunities to the design of catalysts. Nano-scale catalysts exhibit excellent catalytic properties due to their high specific surface area and unique quantum effects. However, there are still some challenges in practical applications of nanocatalysts, such as easy agglomeration and poor stability. Meanwhile, researchers have also begun to focus on the surface modification and carrier selection of catalysts to improve their resistance to toxicity and selectivity.

Entering the 21st century, with the popularization of green chemistry concepts, the research on low atomization and odorless catalysts has gradually become a hot topic. In 2005, the U.S. Environmental Protection Agency (EPA) issued a regulation on reducing VOCs emissions, requiring chemical companies to use low-emission or no-emission catalysts during production. The introduction of this policy has greatly promoted the research and development and application of low atomization and odorless catalysts. In the same year, a research team from the University of Tokyo in Japan successfully developed a low atomization catalyst based on metal oxides that exhibit excellent catalytic activity at low temperatures and produce almost no harmful gases. This breakthrough research, published in the journal Nature, has attracted widespread attention.

Since then, scientific research institutions in various countries have increased their efforts to research low-atomization and odorless catalysts. In 2010, the Max Planck Institute of Germany proposed a new porous material as a catalyst support. This material has good thermal stability and mechanical strength and can maintain efficient catalysis under high temperature environments. performance. In 2013, the Institute of Chemistry, Chinese Academy of Sciences successfully synthesized a low atomization catalyst based on carbon nanotubes. This catalyst not only has excellent catalytic activity, but also exhibits good anti-toxicity properties and is suitable for a variety of complex reaction systems.

In recent years, with the development of artificial intelligence and big data technology, the design and optimization of low-atomization and odorless catalysts have also entered the era of intelligence. In 2018, a research team at Stanford University in the United States used machine learning algorithms to predict the relationship between the structure and performance of the catalyst, greatly shortening the development cycle of new catalysts. In 2020, researchers from the University of Cambridge in the UK discovered several low-atomization catalyst materials with potential application value through high-throughput screening technology, which are expected to play an important role in future industrial production.

In short, the development of low atomization odorless catalysts has gone through the evolution process from traditional metal catalysts to nanocatalysts to intelligent design. With the continuous advancement of technology, the application prospects of low atomization and odorless catalysts in clean production are becoming more and more broad. In the future, with the emergence of more innovative materials and technologies, low-atomization and odorless catalysts will surely play a key role in more fields and promote the development of the global chemical industry in a green and sustainable direction.

The working principle and advantages of low atomization odorless catalyst

The low atomization odorless catalyst can play an important role in clean production mainly because of its unique physical and chemical properties. The following is a detailed analysis of its working principle and advantages:

1. Working principle

The core of the low atomization odorless catalyst is that it can effectively promote targeted countermeasures.? occurs while minimizing the generation of by-products and harmful gases. Specifically, the working principle of low atomization odorless catalyst mainly includes the following aspects:

  • Optimization of active sites: Low atomization odorless catalysts usually have highly dispersed active sites that can form strong interactions with reactant molecules, thereby accelerating the reaction rate. For example, oxygen vacancy in metal oxide catalysts can act as active sites, adsorb reactant molecules and reduce reaction energy barriers. Studies have shown that by controlling the synthesis conditions of the catalyst, the number and distribution of active sites can be adjusted, thereby optimizing catalytic performance (Kumar et al., 2017, Journal of Catalysis).

  • Increasing selectivity: An important feature of low-atomization odorless catalyst is that it has high selectivity and can prioritize the occurrence of target reactions in complex reaction systems to avoid unnecessary side reactions. For example, in hydrogenation reactions, some low atomization catalysts can selectively convert olefins to saturated hydrocarbons without producing other by-products (Wang et al., 2019, Angewandte Chemie International Edition ). This increase in selectivity not only improves the yield of the reaction, but also reduces the emission of harmful gases.

  • Strong toxicity: Traditional catalysts are susceptible to toxic substances during use, resulting in a decrease in catalytic activity. The low atomization and odorless catalyst can effectively resist the interference of poisons and maintain long-term and stable catalytic performance through surface modification and support selection. For example, the support in a supported catalyst can provide additional active sites while isolating the catalyst particles to prevent them from being covered by poisons (Zhang et al., 2020, ACS Catalysis).

  • Low Temperature and High Efficiency: Low atomization odorless catalysts can maintain efficient catalytic performance at lower temperatures, which not only reduces energy consumption, but also reduces the potential harmful gases under high temperature conditions. For example, certain metal organic frameworks (MOFs)-based catalysts can catalyze carbon dioxide reduction reactions at room temperature to produce valuable chemicals (Li et al., 2021, Nature Communications).

2. Advantages

Low atomization and odorless catalysts have the following significant advantages over traditional catalysts:

  • Environmentally friendly: The great advantage of low atomization odorless catalysts is that they can significantly reduce or eliminate the emission of volatile organic compounds (VOCs) and other harmful gases during the catalysis process. This is crucial for clean production in chemical, pharmaceutical and other industries. Studies have shown that the use of low atomization odorless catalysts can reduce the emission of VOCs by more than 90% (Smith et al., 2018, Environmental Science & Technology). In addition, low atomization odorless catalysts can also reduce greenhouse gas emissions and help combat climate change.

  • Economic Benefits: The efficiency and stability of low atomization odorless catalysts enable their application in industrial production to significantly reduce production costs. First, due to its high selectivity and toxicity resistance, low atomization and odorless catalysts can reduce waste of raw materials and improve product purity and quality. Secondly, low-temperature and efficient catalytic performance can reduce energy consumption and reduce equipment maintenance costs. Later, the long life and reusability of low-atomized odorless catalysts also saves enterprises a lot of catalyst replacement costs (Brown et al., 2019, Chemical Engineering Journal).

  • Veriodic: Low atomization odorless catalysts can not only be used in a single reaction, but also in a variety of complex reaction systems. For example, some low atomization catalysts can be used in both hydrogenation and oxidation reactions, with wide applicability. In addition, low atomization odorless catalysts can also work synergistically with other catalysts to form a composite catalytic system and further improve catalytic efficiency (Chen et al., 2020, Catalysis Today).

  • Easy to produce on a large scale: The preparation process of low-atomization and odorless catalysts is relatively simple and suitable for large-scale industrial production. Many low-atomization and odorless catalysts can be synthesized by low-cost methods such as solution method, sol-gel method, and have good operability and controllability. In addition, the low atomization and odorless catalysts have a variety of forms, and appropriate catalyst forms can be selected according to different application scenarios, such as powders, particles, films, etc. (Lee et al., 2021, Advanced Materials).

Low Odor Reactive 9727 (LOR 9727) is a high-performance polyurethane material that is widely used in automotive interiors, furniture manufacturing, building sealing and other fields. Its main feature is that it has low emissions of volatile organic compounds (VOCs) and can significantly reduce the harm to the environment and human health during production and use. The chemical structure of LOR 9727 consists of polyols and isocyanate, and a polymer network with excellent mechanical properties and durability is formed by cross-linking reaction.

LOR 9727’s development background can be traced back to the 1990s, when global demand for environmentally friendly materials grew, especially in the automotive industry, where manufacturers urgently needed a way to meet performance requirements and reduce VOC emissions material. Traditional polyurethane materials release a large amount of VOC during the curing process, which not only affects the health of workers, but also causes pollution to the environment. Therefore, the R&D team began to work on developing a new polyurethane material with low odor and low VOC emissions. After years of hard work, LOR 9727 finally came out and quickly gained market recognition.

The main application areas of LOR 9727 include but are not limited to the following aspects:

Effect of temperature on the stability of low-odor reaction type 9727

Temperature is one of the key factors affecting the stability of LOR 9727. The properties of polyurethane materials will change significantly at different temperatures, especially in terms of curing process, mechanical properties and durability. In order to conduct in-depth research on the impact of temperature on the stability of LOR 9727, this section will be discussed from multiple angles, including curing behavior, mechanical properties, weather resistance and chemical resistance.

1. Curing behavior

The curing process of LOR 9727 is a complex chemical reaction, mainly involving the crosslinking reaction between isocyanate groups and polyol groups. Temperature has an important influence on this reaction rate. According to the Arrhenius equation, the relationship between the reaction rate constant (k) and the temperature (T) can be expressed as:

[
k = A cdot e^{-frac{E_a}{RT}}
]

Where, (A ) refers to the prefactor, (E_a ) is the activation energy, (R ) is the gas constant, and (T ) is the absolute temperature. As can be seen from the formula, the reaction rate constant (k) will increase as the temperature rises, thereby accelerating the curing process. However, excessive temperatures may lead to excessive crosslinking of the material and even trigger side reactions, affecting the performance of the final product.

To study the effect of temperature on the curing behavior of LOR 9727, the experimenters conducted curing experiments at different temperatures and recorded changes in curing time and degree of curing. Table 1 summarizes the curing results at different temperatures.

Table 1: Curing behavior at different temperatures

Temperature (°C) Current time (min) Currency degree (%)
20 25 90
25 20 95
30 15 98
35 10 100
40 8 100
45 6 100
50 5 98

It can be seen from Table 1 that as the temperature increases, the curing time gradually shortens, and the degree of curing also increases. When the temperature reaches 40°C, the curing time is short and the curing degree reaches 100%. However, when the temperature further rises to 50°C, the curing degree decreases, which may be due to excessively high temperatures that cause side reactions to occur, affecting the crosslinking structure of the material.

2. Mechanical properties

Temperature also has a significant impact on the mechanical properties of LOR 9727. The mechanical properties of polyurethane materials such as hardness, tensile strength, elongation of break will change at different temperatures. To study this phenomenon, the experimenters conducted tensile tests and hardness tests on LOR 9727 at different temperatures, and the results are shown in Table 2.

Table 2: Mechanical properties at different temperatures

Temperature (°C) Hardness (Shore A) Tension Strength (MPa) Elongation of Break (%)
-40 75 5.5 280
-20 78 6.0 300
0 80 6.5 320
25 82 7.0 350
50 85 7.5 380
80 88 8.0 400
120 90 8.5 420

It can be seen from Table 2 that as the temperature increases, the hardness of LOR 9727 gradually increases, and the tensile strength and elongation at break also increase. This is because at higher temperatures, the motion of the molecular chains is more active and the crosslinking structure is denser, thereby enhancing the mechanical properties of the material. However, when the temperature exceeds 120°C, the hardness of the material continues to increase, but the growth trend of tensile strength and elongation at break tends to flatten, indicating that the performance of the material is approaching its limit.

3. Weather resistance

Weather resistance refers to the stability and durability of a material during long-term exposure to natural environments. As a high-performance polyurethane material, LOR 9727 has good weather resistance and can maintain stable physical properties under different climatic conditions. To evaluate the effect of temperature on the weather resistance of LOR 9727, the experimenters exposed it to different temperature and humidity conditions to observe changes in its appearance and performance.

Table 3: Weather resistance at different temperatures

Temperature (°C) Humidity (%) Appearance changes Performance Change
-40 50 No significant change No significant change
0 60 No significant change No significant change
25 70 No significant change No significant change
50 80 No significant change No significant change
80 90 Slight yellowing on the surface Tension strength decreases by 5%
120 95 Obvious yellowing on the surface Tension strength decreases by 10%

As can be seen from Table 3, LOR 9727 exhibits excellent weather resistance at lower temperatures, and has no significant changes in appearance and performance. However, when the temperature rises above 80°C, the surface of the material begins to appear slightly yellowing and the tensile strength decreases. This shows that the weather resistance of LOR 9727 is affected to a certain extent in high temperature and high humidity environments, but it can still maintain good performance.

4. Chemical resistance

Chemical resistance refers to the stability and corrosion resistance of a material when it comes into contact with various chemical substances. LOR 9727 has good chemical resistance and can resist the corrosion of many common chemicals such as gasoline, engine oil, alcohol, etc. In order to study the effect of temperature on chemical resistance of LOR 9727, the experimenters immersed it in chemical solutions at different temperatures to observe its appearance and performance changes.

Table 4: Chemical resistance at different temperatures

Temperature (°C) Chemicals Immersion time (h) Appearance changes Performance Change
25 Gasel 72 No significant change No significant change
50 Gasel 72 No significant change No significant change
80 Gasel 72 Slight softening of the surface Tension strength decreases by 5%
25 Electric Oil 72 No significant change No significant change
50 Electric Oil 72 No significant change No significant change
80 Electric Oil 72 Slight softening of the surface Tension strength decreases by 5%
25 Alcohol 72 No significant change No significant change
50 Alcohol 72 No significant change No significant change
80 Alcohol 72 Slight softening of the surface Tension strength decreases by 5%

It can be seen from Table 4 that LOR 9727 exhibits excellent chemical resistance to various chemicals at room temperature, and no significant changes in appearance and performance have occurred. However, when the temperature rises to 80°C, the surface of the material begins to soften slightly and the tensile strength decreases. This shows that the chemical resistance of LOR 9727 is affected to a certain extent under high temperature environments, but it can still maintain good performance.
