Sebacic acid Usage And Synthesis
The main method of preparation (1) Castor oil is as raw material, ricinoleate is separated from castor oil, with the condition of inflating and 280~300℃, caustic soda proceeds alkali fusion and the reaction is heated for 10h, sebum acid sodium salt can obtain, deputy product is 2-octanol. The sodium salt is dissolved in water, adding sulfuric acid to neutralize, after bleaching, the solution is cooled to precipitate sebum acid, it is washed with cold water, and finally recrystallized.
CH3 (CH2) 5CH (OH) CH2CH = CH (CH2) 7COOH +
2NaOH → CH3 (CH2) 5CH (OH) CH3 + NaOOC (CH2) 8COONa + H2
NaOOC (CH2) 3COONa + H2SO4 → HOOC (CH2) 8COOH + Na2SO4
(2) Adipic acid (hexane diacid) is as raw material to synthesize. Adipic acid and methanol can proceed esterification reaction to form dimethyl adipate, ion exchange membrane proceeds electrolytic oxidation to get dimer, i.e., dimethyl sebacate, and then reacts with sodium hydroxide to form the disodium salt, hydrochloric acid (or sulfuric acid) is used to neutralize and Sebacic acid can obtain.
Chemical properties, uses and methods of preparation of sebacic acid are edited by Chemicalbook andy.(2016-12-04)
Chemical properties It is white flaky crystal. It is slightly soluble in water, soluble in alcohol and r.

Sebacic acid is widely used in the preparation of sebacic acid esters, such as dibutyl sebacate, dioctyl sebacate, diisooctyl sebacate. These esters can be used as plasticizers for plastics and cold-resistant rubber, as well as for polyamide, polyurethane, alkyd resin, synthetic lubricating oil, lubricating oil additives, spices, coatings, cosmetics, etc. It can also be used as raw material for producing nylon 1010, nylon 910, nylon 810, nylon 610, nylon 9 and high temperature resistant lubricating oil diethylhexyl ester. It is also the raw material 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 rubber plasticizers, softeners, and solvents.

Uses 1. Sebacic acid can be used as cold plasticizer, nylon resins and other raw material.
2. It can be used as analytical reagents, etc.
3. Sebacic acid is mainly used as sebate plasticizer and nylon molding resin raw material, it is also used for high-temperature lubricant raw material. Its main product is methyl ester, isopropyl, butyl, octyl, nonyl phenyl ester and methyl ester, common ester is dibutyl sebacate and dioctyl sebacate. Sebacic acid plasticizers can be widely used in polyvinyl chloride, alkyd resins, polyester resins and polyamide molding resin due to its low toxicity and high temperature performance, so it is often used in the resin of some special purposes. Nylon molding resin which producted by sebacic acid has high toughness and low moisture absorption, it can also be processed into many special-purpose products. Sebacic acid is also rubber softener, surfactant, coating and fragrance raw materials.
4. Sebacic acid is used as GC Less tail agent, separation and analysis of fatty acids, it can be used to precipitate and quantitative determination of thorium, separation of thorium, cerium and other rare earth elements. Plasticizers, synthetic resins and synthetic fibers.
Production method It can be obtained by raw materials of natural castor oil or adipic acid monoester. Sebacic acid can be obtained by polymerization reaction with ethylene and carbon tetrachloride, but the world's industrial production of sebacic acid almost all use castor oil as raw material.
1. castor oil cracking process: under effect of alkali, castor oil is heated to proceed hydrolysis and generates sodium castor oil soap, then sulfuric acid is added to acidolysis and ricinoleic acid is obtained; in the presence of diluent cresol , alkali is added and it is heated to 260-280℃ to proceed splitting decomposition and generates sebacic acid and sodium bis octanol and hydrogen, lysate is diluted with water, heated and adding acid to neutralize, double salt is turned into monosodium salt; and then neutralized liquid after actived carbon decoloration is boiling and added acid, sebacic acid monosodium salt turns into sebacic acid and seeds out, after separation, drying can derive products. Material consumption fixed: castor oil (industrial) 2100kg/t, sulfuric acid (98%) 1600kg/t, caustic soda (95%) 1200kg/t, cresol (industrial) 100kg/t. 2.Oil n-decane fermentation method: n-decane is obtained by the separation of 200 # solvent oil or 166-182℃ fraction, sebacic acid is obtained by 19-2 Solutions Candida lipolytica fermentation.
2. New cyclopentanone method: palladium salt-copper or iron is as catalyst, in the solvent of ethanol, propanol or other alcohol, in the eased condition of low temperature of 40-60℃ and ordinary pressure, cyclopentene is oxidated by air to generate cyclopentanone, then it is obtained by oxidated of iron catalyst and titanium.

Sebacic acid, also known as 1, 10-decanedioic acid, belongs to aliphatic dibasic acid. Sebacic acid was present in the leaves of flue-cured tobacco, burley tobacco and aromatic tobacco. Sebacic acid was white crystal in flake form at room temperature. Slightly soluble in water, sebacic acid was insoluble in benzene, petroleum r, carbon tetrachloride. In contrast, sebacic acid was soluble in ethanol and ethyl r. Irritant to the eyes, respiratory system and skin irritation, sebacic acid oral harmful. However, sebacic acid was low toxic and flammable.

Description Sebacic acid is a dicarboxylic acid with structure (HOOC)(CH2)8(COOH), and is naturally occurring.
In its pure state it is a white flake or powdered crystal. The product is described as non-hazardous, though in its powdered form it can be prone to flash ignition (a typical risk in handling fine organic powders).
Sebaceus is Latin for tallow candle, sebum (tallow) is Latin for tallow, and refers to its use in the manufacture of candles. Sebacic acid is a derivative of castor oil, with the vast majority of world production occurring in China which annually exports over 20,000 metric tonnes, representing over 90 % of global trade of the product.
In the industrial setting, sebacic acid and its homologues such as azelaic acid can be used in plasticizers, lubricants, hydraulic fluids, cosmetics, candles, etc. Sebacic acid is also used as an intermediate for aromatics, antiseptics, and painting materials.
Chemical Properties white powder
Uses Decanedioic acid was named by Thenard LJ (1802) from the Latin sebaceus(tallow candle) or sebum (tallow) in reference to its use in the manufacture of candles. Thenard LJ isolated this compound from distillation products of beef tallow. In 1954, it was reported that it was produced in excess of 10,000 tons annually by alkali fission of castor oil. Sebacic acid and its derivatives, as azelaic acid, have a variety of industrial uses as plasticizers, lubricants, diffusion pump oils, cosmetics, candles, etc. It is also used in the synthesis of polyamide, as nylon, and of alkyd resins. An isomer, isosebacic acid, has several applications in the manufacture of vinyl resin plasticizers, extrusion plastics, adhesives, ester lubricants, polyesters, polyurethane resins and synthetic rubber.
General Description White granular powder. Melting point 153°F. Slightly soluble in water. Sublimes slowly at 750 mm Hg when heated to melting point.
Air & Water Reactions Insoluble in water.
Reactivity Profile Sebacic acid reacts exothermically to neutralize bases, both organic and inorganic. May react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Can react with active metals to form gaseous hydrogen and a metal salt. Such reactions are slow in the dry, but systems may absorb enough water from the air to allow corrosion of iron, steel, and aluminum parts and containers. Reacts slowly with cyanide salts to generate gaseous hydrogen cyanide. Reacts with solutions of cyanides to cause the release of gaseous hydrogen cyanide. May generate flammable and/or toxic gases and heat with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. May react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Can be oxidized exothermically by strong oxidizing agents and reduced by strong reducing agents. May initiate polymerization reactions.
Fire Hazard Flash point data for Sebacic acid are not available. Sebacic acid is probably combustible.
Purification Methods Purify sebacic acid via the disodium salt which, after crystallisation from boiling water (charcoal), is again converted to the free acid. The free acid is crystallised repeatedly from hot distilled water or from Me2CO/pet r and dried under vacuum. [Beilstein 2 IV 2078.]
