production method | castor oil and sodium hydroxide aqueous solution are heated and cracked to generate 10-hydroxydecanoic acid, then 10-bromodecanoic acid was obtained by bromination of hydrogen bromide, and then ethyl 10-bromodecanoate was obtained by esterification of ethyl 10-bromodecanoate with ethanol in the presence of sulfuric acid. The latter reacted with methyl mercaptan and sodium metal to obtain ethyl 10-methylthiodecanoate, this product was further prepared by oxidation with hydrogen peroxide. |
