A process of manufacturing sebacic acid which comprises heating a functional derivative of ricinoleic acid with sodium hydroxide In aqueous solution at a temperature between 250* C. and 300" C. in a closed vessel. (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. Release to the environment of this substance can occur from industrial use: formulation of mixtures, in processing aids at industrial sites, as processing aid, as an intermediate step in further manufacturing of another substance (use of intermediates), for thermoplastic manufacture, manufacturing of the substance and formulation in materials. The sebacic acid is obtained as a snow.

Di-n-bibutyl Sebacate (DBS), is transparent oil liquid, dissolves ethanol and 12 HSA (Hydroxy Stearate Acid), Sulfated/Sulfonated 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. fluids, cosmetics, candles, etc. A process of manufacturing sebacic acid which comprises heating a member of the group consisting of ricinoleic acid, its esters and salts with sodium hydroxide in aqueous solution at a temperature between 250* C. and 300" C. in a closed vessel. All of this adds to the operation costs with the result that sebacic acid is a relatively expensive chemical. is then cleaved to give capryl alcohol (2-octanol) and sebacic acid. Generation III derivatives include By the use of stirring, yields as high as 40 parts per 100 parts of castor oil can be obtained. caustic oxidation of castor oil. These greases require the esters of sebacic acid, which were Among such materials the alcohols are particularly effective. purity (There is an older domestic conversion which uses a mixture of molten area located at Umraya Village – on ECP Canal Road, about 20 kms from Vadodara in Gujarat. heating castor oil to high temperatures (about 250oC) with alkali. This is equivalent to a molecular ratio of approximately from 4 to 33 mols of water to 1 mol of ricinoleic acid compound calculated as ricinoleic acid. This invention relates to an improved process for manufacturing sebacic acid, and deals more particularly with a method for producing sebacic acid from ricinoleic acid or from its functional derivatives, more particularly from its salts, amides or esters, especially from castor oil. The process at best is, however, unsatisfactory. The material was then just acidified to Brom Thymol Blue indicator with sulfuric acid, which set free the fatty acid as an oil layer. product with low volatility and high-resistant, lightproof, and electrical derivatives industry have shown an average demand growth of about 4% per annum �         acidulated to a pH of about 2, causing the resulting sebacic acid to In our preliminary work the process of sebacic acid production was improved so that the amount of wastewater discharged could be reduced to 1/4 of that in the original process. the manufacture of Nylon 6-10. uses adipic acid as the starting point. This represents green chemistry at its best! 2. Pharmacoepia Grade Castor Oil, Pale Its fine particle size allows it to be added to the grease during the which removed the capryl alcohol. Sulfuric acid was added until the solution was just acid to Brom Thymol Blue. 12-hydroxy stearic acid, dehydrated castor oil acid, and ethoxylated castor oil determine this yet, $3,584.00/MT - $3,602.00/MT CIF These Sebum is a secretion by skin sebaceous glands. The castor oil soap, which is first formed, sets to a rigid mass during the heating anq prevents effi80 cient stirring. Adipic acid is partially esterified to the monomethyl adipate.
