Unsaturated coconut and/or palm kernel fatty alcohol

摘要

Unsaturated coconut and/or palm kernel fatty alcohols are new. Unsaturated coconut and/or palm kernel fatty alcohols have an iodine number of 65-85, and comprise a mixture of unsaturated fatty alcohols of formula (I). R1 = optionally saturated, optionally linear 14-20C alkyl group. An Independent claim is also included for the preparation of the coconut and/or palm kernel fatty alcohols, comprising (a) fractionating coconut and/or palm kernel fatty acid methyl ester to obtain mostly 18-20C fractions; (b) fractionating the product of (a) in a mixture of mostly saturated distillate and a mostly unsaturated bottom product; and (c) hydrating the bottom product to obtain specific alcohols with double bonds.
