Sebacic Acid Powder Usage and Synthesis.

Sebacic acid is an important chemical raw material with a wide range of applications. Applications of sebacic acid include polymers, plasticizers, additives, degradable plastics and other materials. Among them, the highest percentage of sebacic acid content is used in polymers. Sebacic acid is also widely used in esters, such as dibutyl sebacate, dioctyl sebacate, and diisooctyl sebacate.

These esters can be used as plasticizers for plastics and cold-resistant rubber, and can also be used to make polyamides, polyurethanes, alkyd resins, synthetic lubricants, lubricant additives, as well as fragrances, coatings, cosmetics, and so on. In addition, sebacic acid can also be used in the production of nylon 1010, nylon 910, nylon 810, nylon 610, nylon 9 and high-temperature lubricants such as diethylhexyl ester.

Uses of Sebacic Acid.

It is mainly used as raw material of sebacate plasticizer and nylon molding resin, and also used as raw material of high temperature resistant lubricant. Its main ester products are methyl ester, isopropyl ester, butyl ester, octyl ester, nonyl ester and benzyl ester, and the commonly used esters are dibutyl sebacate and dioctyl sebacate.

Sebacic acid plasticizer can be widely used in polyvinyl chloride, alkyd resins, polyester resins and polyamide molding resins, due to its low toxicity and high temperature performance, so it is often used in some special-purpose resins.

Nylon molding resin produced with sebacic acid has high toughness and low hygroscopicity, and can also be processed into many special-purpose products. Sebacic acid is also a softener for rubber, a surfactant, and a raw material for coatings and fragrances.

Gas chromatography tailing agent, separation and analysis of fatty acids, can be used to precipitate and quantitative determination of thorium, and make thorium and cerium and other rare earth yuanso separation. Plasticizers, synthetic resins and synthetic fibers.

Pharmacological effect of Sebacic Acid.

Product Method of Bulk Sebacic Acid Powder.

Natural castor oil or monoester of adipic acid as raw material. With ethylene, carbon tetrachloride polymerization reaction can also get sebacic acid, but at present the world's industrial production of sebacic acid is almost entirely with castor oil as raw material.

1. castor oil cracking method castor oil under the action of alkali heating hydrolysis to generate sodium soap ricinoleate, and then add sulfuric acid acid to generate ricinoleic acid; in the presence of diluent cresol, add alkali heating to 260-280 ℃ for cracking, sebacic acid and sec-octanol disodium salt and hydrogen, cracked diluted with water, heating and acid neutralization, the disodium salt into a monosodium salt; and then decolorized with activated carbon after the neutralization of the liquid boiling and adding acid The monosodium salt of sebacic acid will become sebacic acid crystal precipitation, and then after separation and drying, the finished product will be obtained.

Raw material consumption quota: castor oil (industrial) 2100kg/t, sulfuric acid (98%) 1600kg/t, caustic soda (95%) 1200kg/t, cresol (industrial) 100kg/t.

2. Petroleum n-decane fermentation method using 200 # solvent oil or 166-182 ° C fraction of n-decane, separated from the 19-2 Pseudosciaenic yeast fermentation to produce sebacic acid.

3. Neocyclopentanone method with palladium salt - copper or iron as catalyst, in ethanol, propanol or other alcohols in the solvent, at 40-60 ℃ low temperature and atmospheric pressure under the conditions of mitigation, the cyclopentene with air oxidation to produce cyclopentanone, and then oxidized and dimerized with an iron catalyst to become
