Introduction to edit


HOOC (CH2) 8 cooh and sebacic acid.Refinement for white scaly crystalline, industrial products with a light yellow, melting temperature of 134.5 ℃.Mainly by castor oil as raw material for making, is one of the agriculture and forestry chemical products.
Sebacic acid is with castor oil and alkali distillation, the earliest later developed synthetic method, is currently developing petroleum fermentation (see fermentation) corresponding normal alkanes was making new route of sebacic acid.Is now widely used in industry castor oil alkaline hydrolysis is within the reaction kettle, castor oil saponification reaction with alkali liquor under 100 ℃ ricinoleic acid sodium and glycerin.Adding isolated ricinoleic acid sodium and generate ricinoleic acid of sulfuric acid and alkaline hydrolysis reaction with alkali, reaction temperature 260 ~ 280 ℃, using low voltage or high voltage.Reaction sebacic acid double salt and sodium 2 - octanol and hydrogen.Finally obtained with sulfuric acid neutralization, decolorization, crystallization, drying is tasted, the total yield over 40%.Another production of sebacic acid method was developed by Japan agms industrial company adipic acid electrolytic oxidation method, compared with castor oil alkali solution to the high cost, so the mass production.
Sebacic acid widely used, mainly used for preparing sebacic acid esters, such as sebacic acid dioctyl ester as a plastic, cold-resistant rubber plasticizer, can also be used for producing polyamide, polyurethane, alkyd resin, synthetic lubricating oil, lubricating oil additives.Sebacic anhydride curing agent for epoxy resin, and spices, coatings, cosmetics, etc.
