Process flow and difference:
Mix oleic acid and acetic acid, add it to the reactor, pass in ozone, control the reaction temperature, check the reaction progress. When the basic reaction of the raw materials is complete, stop the ozone, distill off the solvent, and use water The material was washed, and Azelaic acid was extracted with hot water to obtain an industrial-grade Azelaic acid product.
Advantages: 1. Compared with potassium permanganate, the reaction can be better controlled with ozone, the reaction is mild, the mechanical impurities are less, and the product color is low.
2. The product with high purity can be obtained by water extraction at one time.
3. Use acetic acid to promote the reaction. Compared with concentrated sulfuric acid, the reaction is milder. The color of the product obtained by the reaction is lower.
Product application:
1. Azelaic acid plasticizer is an excellent cold-resistant plasticizer. It is suitable for artificial leather, film, sheet, wire and cable sheath, etc. For nylon, molding resin, polyamide hot melt, polyester and polyester. Amide fibers, polyester films, adhesives, polyurethane elastomers, raw materials for cable coatings and lubricants, capacitors for electronics, medicine, and the production of plasticizer Azelaic acid dioctyl ester.
2. Azelaic acid octyl, decyl, tridecane and other diester lubricants have good viscosity-temperature characteristics and high viscosity index. Especially branched alcohol diester lubricants have high flash point, low oxidative viscosity, and low temperature performance Well, it has excellent viscosity/temperature characteristics and good addition sensitivity. Mainly used in aviation turbine engine lubricating oil, precision instrument oil, synthetic compressor oil, automobile engine oil, metal processing oil, synthetic grease base oil and plastic, chemical fiber and other fine chemical fields.
3.Synthetic fiber
4. Adding high-purity Azelaic acid or its salts to the electrolytic solution of electrolytic capacitors can significantly increase the service life of electrolytic capacitors. The electrolyte composed of ethylene glycol/phosphoric acid/water can produce aluminum electrolytic capacitors with small current leakage and high spark current.
5. Azelaic acid has applications in perfumes, oils, resists, flocculants, flame retardants and stabilizers, lubricants, and raw materials for polyamide resins.
