Abstract
A process for the preparation of a compound can have the formulawherein R1, R2 and R3 are independently selected from hydrogen and acyl groups, wherein at least one of R1, R2 and R3 is a branched chain long acyl group of the formulawherein n is from 9 to 21 and m is 2n, and wherein p is from 0 to 4, wherein the other of R1, R2 and R3 are selected from short acyl groups of the formulawherein q is from 0 to 4; the process comprising the steps of: (1) providing an unsaturated compound having the formula(2) if at least one of R1, R2 and R3 is hydrogen, optionally acylating the compound; and (3a) (i) hydroxylating the unsaturated long acyl group and (ii) acylating the hydroxy long acyl group, or (3b) reacting the unsaturated long acyl group with a carboxylic acid.
