                          Sebacic acid
    Sebacic acid was first obtained by distillation of castor oil with alkali , after the development of synthetic methods currently being developed oil n-alkanes fermented ( see fermentation process ) made ??a new route sebacic acid . Castor oil is now widely used in industry alkali solution is in the reactor, the alkali saponification reaction of castor oil and castor oil, sodium and glycerol generated at 100 ℃. Castor oil , and sodium sulfate was added to generate separated ricinoleic acid , an alkali solution and then with a base , the reaction temperature is 260 ~ 280 ℃, low pressure or high pressure . Reaction of sebacic acid disodium salt and 2 - octanol and hydrogen. And finally by sulfuric acid , bleaching, crystallized and dried to obtain a pure product , the total yield of 40 %. Another method is sebacic acid Asahi Chemical Industry Co., adipic developed electrolytic oxidation method, an alkali solution of a high cost as compared with castor oil .

    Uses:

    Mainly used for making esters of sebacic acid esters such as dioctyl sebacate as plastic , cold rubber plasticizer can also be used to prepare polyamides, polyurethanes, alkyd resins, synthetic lubricants, lubricant additives. Poly (sebacic anhydride) epoxy resin curing agent , and perfume , paint , cosmetics, and the like.
