Upon further acidification of the latter solution to a pH of about 4 with a mineral acid such as sulfuric acid, the sebacic acid is precipitated as a white mass. where the ricinoleic acid undergoes a series of reactions with evolution of It has a role as a human metabolite and a plant metabolite. A process of manufacturing sebacic acid which comprises heating castor oil with a member of the group consisting of alkali metal hydroxides and alkali metal carbonates in aqueous T5 solution at a temperature between 2500 C. and 300° C. under a superatmospheric pressure at least equivalent to the vapor tension of the reaction mixture. Furthermore, when metal or metal oxide catalysts are employed, the fatty acids usually become contaminated with soluble metal salts. Sebacic acid is widely used in various end use industries including lubricants, plasticizers, hydraulic fluids, candles, and cosmetics. The fatty acid residue amounted to 20.5% by weight of the castor oil used, and had a saponification number of 124.5 and an acid number of 121.

Furthermore, the process has always heretofore been of such a character as to be applicable only to batch operation; that is to say, a batch of castor oil and alkali hydroxide are heated together until the reaction is complete and the reaction kettle is then emptied to receive a fresh batch of castor oil and alkali. One object of the present invention is to lower the cost of making sebacic acid by the use of a more efficient process according to which sebacic acid is obtained in higher yields and purity by a method in which the solidification of the castor oil soaps during the heating is prevented, thereby eliminating charring, local overheating and pyrogenic decomposition. (b) The process carried out as described in detail above, but without any agitation or stirring during the reaction period, gave a yield of sebacic acid of 44.6% by weight. Since castor oil is principally the tri-ricinoleic glyceride, one mol of castor oil requires a correspondingly greater molecular amount of alkali metal hydroxide, namely not less than six equivalents. Sebacic Acid from The People's Republic of China Investigation No. The reaction is 100% renewable and involves the use of no solvents or petrochemicals.

Jinghua Chemical Plant, China�s largest Sebacic acid producers manufacture It is then filtered, water acid have a variety of industrial uses in plasticizers, lubricants, hydraulic which removed the capryl alcohol. The reaction product in water may be steamdistilled to remove the octanol-2, or the octanol-2 may be removed later by steam distillation of the fatty acid component after the sebacic acid has been separated. The report analyzes, tracks, and presents the worldwide market size of the leading players in each region around â¦ The octanol-2 obtained by steam distillation is a colorless liquid and usually contains some methyl hexyl ketone and some moisture. hydrolysis of dimethyl sebacate to sebacic acid. Since the reaction ordinarily requires from 8 to 24 hours for completion, depending upon the size of the batch and the efficiency of the heating and stirring, either a large number of small reaction vessels and the necessary stirring equipment are required, or else very expensive large capacity reactors are necessary in order to produce commercial quantities of sebacic acid of the order required for the coatings and plastics industry. Generation III derivatives include The latter distills off together with water, leaving a hard, dense, stone-like mass, which is extremely difficult to stir and which, upon acidification, yields a mixture of liquid higher fatty acids and sebacic acid. about 85%. Furthermore, the hydrogen evolved under high pressure in the present process might be expected to act as a reducing agent, and thereby prevent the desired reaction from taking place.
