Sebacic acid production line Introduction of sebacic acid produced by sebacic acid production line, English name Decanedioicacid is also known as n-decanedioicacid (n-decanedioicacid) 1,10-decanedioic acid (1,10-decanedioic acid), 1,8-octanedioic acid (1 , 8-octanedicarboxyli cacid), sebacic acid (Sebacicacid). Sebacic acid is an aliphatic dibasic acid and exists in flue-cured tobacco leaves, burley tobacco leaves, and spice tobacco leaves. Sebacic acid is white flaky crystals at room temperature, and industrial products are slightly yellowish. Slightly soluble in water, insoluble in benzene, petroleum ether, carbon tetrachloride, easily soluble in ethanol and ether. Sebacic acid is flammable and low in toxicity. Harmful by mouth, irritating to eyes, respiratory system and skin. It is made from natural castor oil or adipic acid monoester as the raw material, mainly used to prepare sebacic acid esters, and its esters are widely used. The molecular formula of sebacic acid is C10H18O4, and the chemical structural formula is HOOC (CH2) 8COOH. Introduction of physical properties of sebacic acid production line

Sebacic acid is widely used, mainly used to prepare sebacic acid esters, and its esters are widely used, 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, perfumes, paints, and cosmetics. It can also be used as a raw material for the production of nylon 1010, nylon 910, nylon 810, nylon 610, nylon 9 and high temperature resistant lubricating oil diethylhexyl ester. It is also a plasticizer, softener and solvent for the production of alkyd resins (used as surface coatings, plasticized nitrocellulose coatings and urea resin varnishes) and polyurethane rubber, cellulose resins, vinyl resins and synthetic rubbers raw material

Sebacic acid production line Sebacic acid was first obtained by castor oil plus alkali retorting. Later, synthetic methods were developed. A new route for the production of sebacic acid from petroleum n-paraffins is currently being developed.
Production method of sebacic acid production line (1) Castor oil cracking method: Castor oil is heated and hydrolyzed under the action of alkali to form sodium ricinoleic acid soap, and then added with sulfuric acid to produce ricinoleic acid; in the presence of diluent cresol, alkali is added Heated to 260-280 ° C for cracking to produce disodium sebacate, secondary octanol and hydrogen. After the lysate is diluted with water, it is heated and neutralized with acid to turn the double sodium salt into monosodium salt; then decolorize with activated carbon, The neutralizing solution is boiled and acid is added to make the sebacic acid monosodium salt become sebacic acid crystals and precipitated, and then separated and dried to obtain the finished product. Raw material consumption quota: castor oil (industrial product) 2100kg / t, sulfuric acid (98) 1600kg / t, caustic soda (95) 1200kg / t, cresol (industrial product) 100kg / t.
(2) Petroleum n-decane fermentation method: using n-decane separated by 200 # solvent oil or 166-182 ° C fractions, sebacic acid can be prepared by fermentation with 19-2 Candida lipolytica.
(3) New cyclopentanone method: using palladium salt-copper or iron as the catalyst, in the solvent of ethanol, propanol or other alcohols, under the mild conditions of low temperature of 40-60 and normal pressure, use cyclopentene Air oxidation produces cyclopentanone, which is then oxidized and dimerized with iron catalyst to form sebacic acid.
Raw materials upstream of the sebacic acid production line: castor oil, n-decane, cyclopentene.
Downstream products of sebacic acid production line: sebacic acid, various esters of sebacic acid. Such as dibutyl sebacate, dioctyl sebacate, diisooctyl sebacate.
