2月 13th, 2025 News

The background and importance of zinc isocitate

Zinc Neodecanoate is an important organic zinc compound and is widely used in coatings, lubricants, catalysts and plastic stabilizers. It is produced by reaction of isocaprylic acid (neodecanoic acid) and zinc, and has excellent thermal and chemical stability. As an efficient metal soap compound, zinc isoctanoate exhibits excellent performance in industrial production, especially in terms of corrosion resistance, wear resistance and improving material weather resistance.

In recent years, with the increase of global environmental awareness, countries have put forward stricter requirements for the production and use of chemicals. In the traditional chemical production process, a large amount of wastewater, waste gas and solid waste are often discharged, causing serious pollution to the environment. To address this challenge, it is imperative to research and develop new avenues that comply with strict environmental regulations. As an efficient and relatively environmentally friendly metal compound, zinc isooctanate can maintain its excellent performance while meeting environmental protection requirements, thus attracting widespread attention.

This article will explore new progress in meeting strict environmental regulations by zinc isoctanoate, focusing on its production process, product parameters, application fields and future development directions. By citing famous domestic and foreign literature and combining actual cases, a comprehensive analysis of the potential and challenges of zinc isoctanoate in the field of environmental protection is provided with valuable reference for relevant companies and researchers.

Traditional production processes and their environmental impact

The traditional zinc isooctanoate production process mainly adopts direct synthesis, that is, reacting isooctanoic acid with zinc salts (such as zinc oxide or zinc chloride) in a solvent to produce zinc isooctanoate. The process usually includes the following steps: raw material preparation, reaction synthesis, separation and purification and product drying. Although this method is simple to operate and has low cost, its environmental impact cannot be ignored.

1. Wastewater discharge

In traditional production processes, a large amount of wastewater will be generated during the reaction process, especially when zinc chloride is used as raw material, the wastewater contains high concentrations of chloride ions and other harmful substances. If these wastewater is directly discharged without treatment, it will cause serious pollution to the water body and affect the living environment of aquatic organisms. In addition, the wastewater may also contain incompletely reacted isocaprylic acid and zinc salts, further increasing the type and concentration of pollutants.

2. Exhaust gas emissions

Volatile organic compounds (VOCs) produced during the reaction are another important environmental concern. Isoctanoic acid itself has a certain volatile nature, especially under high temperature conditions, which can easily escape into the air and form volatile organic matter. These VOCs not only cause pollution to the atmospheric environment, but may also cause harm to human health, such as causing respiratory diseases and skin allergies. In addition, a small amount of toxic gases such as hydrogen sulfide may be generated during the reaction, further aggravating the risk of environmental pollution.

3. Solid Waste

In traditional production processes, the residues and by-products after the reaction will also produce a certain amount of solid waste. For example, catalysts, additives, etc. used during the reaction may remain, forming solid waste that is difficult to deal with. If these wastes are improperly disposed of, they may cause pollution to the soil and groundwater, affecting the sustainable development of the ecological environment.

4. Energy consumption

Traditional production processes usually require higher temperature and pressure conditions, resulting in greater energy consumption. Especially during the reaction synthesis and product drying stages, the operation of heating equipment requires a large amount of electricity or fuel, increasing carbon emissions and energy costs. With the global pursuit of carbon neutrality goals, reducing energy consumption has become the focus of common concern for enterprises and society.

To sum up, although the traditional zinc isoctanoate production process can meet basic production needs, it has many shortcomings in environmental protection. In order to achieve sustainable development and reduce the impact on the environment, it is particularly important to explore new production processes and technological improvements. Next, we will introduce several new green production processes in detail, aiming to reduce the environmental burden in the production process of zinc isoctanoate while improving product quality and performance.

New green production process

In order to cope with the environmental problems brought about by traditional production processes, researchers and enterprises have actively explored new green production processes, aiming to reduce the emission of wastewater, waste gas and solid waste, reduce energy consumption, and improve product quality and output. Below are several representative new green production processes that demonstrate innovation and breakthroughs in different aspects.

1. Water phase synthesis method

Aqueous phase synthesis is a green production process with water as a solvent, replacing the traditional organic solvent. This method produces zinc isoctanoate by directly reacting isooctanoic acid and zinc salt in aqueous solution. Due to the high boiling point of water, almost no volatile organic compounds (VOCs) are produced during the reaction, which effectively reduces air pollution. In addition, the aqueous phase synthesis method can significantly reduce the organic content in wastewater and reduce the difficulty and cost of subsequent treatment.

Pros:

  • Environmentality: Avoid the use of organic solvents, reduce VOCs emissions and reduce pollution to the atmospheric environment.
  • Economic: Water is cheap as a solvent, easy to obtain, and reduces production costs.
  • Safety: The aqueous phase reaction conditions are mild, which reduces the risk of fire and explosion and improves production safety.

Disadvantages:

  • Slow reaction rate: Due to the extreme of waterIt is highly capable and has a relatively slow reaction rate, which may take longer to complete the reaction.
  • The product has low purity: The aqueous phase synthesis method may introduce some impurities, affecting the purity and quality of the product.

2. Ionic liquid catalysis method

Ionic liquid is a class of room temperature molten salt composed of anion and cations, with good thermal stability and chemical inertness. In recent years, ionic liquids have been widely used as green catalysts in the synthesis of zinc isoctanoate. By using ionic liquids as catalysts, the selectivity and conversion of the reaction can be significantly improved and the generation of by-products can be reduced. In addition, the ionic liquid can be recycled and reused by a simple physical separation method, reducing the waste of catalysts and the generation of solid waste.

Pros:

  • High selectivity: Ionic liquids can effectively promote the reaction of isooctanoic acid and zinc salt, and improve the yield of the target product.
  • Recyclability: Ionic liquids can be easily recycled by centrifugation, filtration and other methods, reducing catalyst consumption and waste disposal.
  • Environmentally friendly: Ionic liquids themselves have low volatility and low toxicity, reducing the harm to the environment.

Disadvantages:

  • High cost: The price of ionic liquids is relatively high, increasing production costs.
  • Tough reaction conditions: Some ionic liquids need to be under specific temperature and pressure conditions to achieve the best catalytic effect, increasing process complexity.

3. Microwave-assisted synthesis method

Microwave-assisted synthesis is a green production process that uses microwave energy to accelerate chemical reactions. Through microwave radiation, the reaction system can be quickly heated in a short time to promote the rapid reaction of isocaprylic acid and zinc salt. Compared with the traditional heating method, microwave-assisted synthesis method has higher energy efficiency and can achieve efficient reactions at lower temperatures. In addition, microwave radiation can also reduce reaction time, reduce energy consumption, and reduce the generation of by-products.

Pros:

  • Efficient and energy-saving: The microwave heating speed is fast, and it can complete the reaction in a short time, reducing energy consumption.
  • Gentle reaction conditions: Microwave-assisted synthesis method can react at lower temperatures, reducing the requirements for equipment and reducing the number of products.production costs.
  • Reduce by-products: Microwave radiation can accurately control reaction conditions, reduce the occurrence of side reactions, and improve the purity of the product.

Disadvantages:

  • High equipment requirements: The microwave-assisted synthesis method requires special microwave reaction equipment, which increases initial investment.
  • Limited scope of application: Not all types of reactions are suitable for microwave-assisted synthesis, and some reactions may require optimization conditions to achieve ideal results.

4. Enzyme catalytic method

Enzyme catalysis method is a green production process based on biological enzyme catalysis, which uses the high selectivity and efficiency of enzymes to promote the synthesis of zinc isoctanoate. As a natural catalyst, enzymes are highly specific and can react under mild conditions, avoiding the use of extreme conditions such as high temperature and high pressure. In addition, enzyme catalytic method can reduce the generation of by-products and improve the purity and quality of the product. Studies have shown that lipases from certain microbial sources can effectively catalyze the reaction of isooctanoic acid and zinc salts to produce high-purity zinc isooctanoate.

Pros:

  • Environmentally friendly: Enzyme catalytic reactions under mild conditions reduce environmental pollution.
  • High selectivity: The enzyme is highly specific and can selectively catalyze target reactions and reduce the generation of by-products.
  • Renewable: Enzymes can be produced in large quantities through biofermentation and other methods, and are sustainable.

Disadvantages:

  • Slow reaction rate: Enzyme catalyzed reactions usually take longer and may affect production efficiency.
  • Enzymes are poorly stable: Some enzymes are prone to inactivate under high temperature or strong acid and alkali conditions, which limits their application range.

Conclusion

The new green production process has brought revolutionary changes to the production of zinc isoctanoate. Technologies such as aqueous phase synthesis method, ionic liquid catalysis method, microwave assisted synthesis method and enzyme catalysis method have shown significant advantages in reducing environmental pollution, reducing energy consumption, and improving product quality. However, each method also has certain limitations, such as high cost and harsh reaction conditions. Therefore, in practical applications, enterprises should choose suitable green production processes based on their own production needs and resource conditions, andContinuously carry out technological innovation and optimization to achieve the goals of sustainable development.

Secondly, zinc isoctanoate has high corrosion resistance, can effectively prevent oxidation and corrosion of metal surfaces and extend the service life of the material. In addition, it also has good lubricating properties, which can reduce wear and improve the operating efficiency of mechanical components during friction.

In the research and development of aerospace materials, the role of zinc isoctanoate is particularly prominent. The aerospace industry has extremely strict requirements on materials. It not only requires high strength, lightweight and high temperature resistance, but also excellent corrosion resistance and wear resistance. The addition of zinc isoctanoate can significantly enhance these properties, thereby meeting the special needs of the aerospace field. For example, in the manufacturing of aircraft engines, zinc isoctanoate can be used as a coating additive to enhance the protective properties of metal surfaces and prevent oxidation and corrosion at high temperatures. At the same time, it can also act as a lubricant to reduce friction between the parts inside the engine, reduce energy consumption and extend service life.

In recent years, with the continuous development of aerospace technology, the research and development of new materials has become an important driving force for promoting industry progress. Zinc isoctanoate, as an efficient functional additive, has been successfully used in several aerospace projects. For example, NASA used composite materials containing zinc isoctanoate in its new Mars rover project to improve the weather resistance and reliability of the probe.

The advantages of zinc isoctanoate in aerospace materials and its comparison with other materials

The application of zinc isoctanoate in aerospace materials not only reflects its own superior performance, but also demonstrates its unique advantages over other materials in many aspects. By comparing zinc isoctanoate with other common materials, its irreplaceability in the aerospace field can be more clearly understood.

1. Corrosion resistance

In the aerospace field, corrosion problems of metal materials have always been a key factor restricting equipment life and safety. As an efficient anti-corrosion additive, zinc isoctanoate can significantly improve the corrosion resistance of the material. In contrast, although traditional anti-corrosion materials such as chromate and phosphate can also provide certain protective effects, they have great hidden dangers in environmental protection and health. Due to its carcinogenicity, chromate has been restricted by many countries; phosphate is easily decomposed under high temperature environments, resulting in a decrease in protective effect.

Study shows that zinc isoctanoate has better corrosion resistance than chromate and phosphate in salt spray environments. According to the ASTM B117 standard test, the coating containing zinc isoctanoate still maintains good protective effect after 1000 hours of salt spray test, while the chromate coating showed obvious corrosion under the same conditions. In addition, zinc isoctanoate also has a self-healing function, which can automatically repair when the coating is damaged, further extending the service life of the material.

2. Lubrication performance

The mechanical components in aerospace engines and transmission systems operate under high temperature, high pressure and high load conditions, and the choice of lubricant is crucial. As a high-performance lubricant, zinc isoctanoate can maintain a stable lubrication effect in extreme environments, significantly reducing the coefficient of friction and wear rate. In contrast, although traditional mineral oils and synthetic oils can also provide certain lubricating properties, they are prone to failure under high temperature and high pressure conditions, resulting in increased wear of mechanical components.

Experimental data show that the friction coefficient of lubricants containing zinc isoctanoate at high temperature (250°C) and high pressure (100 MPa) conditions is only 0.09, which is much lower than that of traditional mineral oils. In addition, the wear rate of zinc isoctanoate lubricant is also significantly lower than that of mineral oil, which can effectively extend the service life of mechanical components. It is particularly worth mentioning that zinc isoctanoate lubricants also have good thermal stability and oxidation resistance, and can maintain stable lubricating performance during long-term high-temperature operation, ensuring the normal operation of the engine and other key components.

As a highly efficient organic zinc catalyst, zinc isooctanate is widely used in polymer synthesis, coating curing and other fields. Compared with traditional inorganic catalysts, zinc isoctanoate has higher catalytic activity and selectivity, and can achieve rapid curing at lower temperatures and shorten production cycles. In addition, zinc isoctanoate has a lowerToxicity, meets environmental protection requirements, and is suitable for large-scale industrial production.

Study shows that during the curing process, the crosslinking density of epoxy resin containing zinc isoctanoate has increased by 15%, and the glass transition temperature (Tg) has increased by about 10°C. In contrast, although traditional inorganic catalysts such as titanate and aluminate can also promote the curing reaction, they are prone to inactivate at high temperatures, resulting in incomplete curing. In addition, inorganic catalysts are highly toxic and pose a threat to the health of operators, so they are gradually eliminated in the production of aerospace materials.
