A process can prepare a compound having the formula  

Plasticizers, polymer compositions and processes for making the plasticizers

A process for the preparation of a compound can have the formula wherein R, Rand Rare independently selected from hydrogen and acyl groups, wherein at least one of R, Rand Ris a branched chain long acyl group of the formula wherein n is from 9 to 21 and m is 2n, and wherein p is from 0 to 4, wherein the other of R, Rand Rare selected from short acyl groups of the formula wherein 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 R, Rand Ris 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.

Process

The present invention relates to a process for preparing a lactone. The process comprises the steps of reacting an aldehyde with an organic halide in a carbon chain extension reaction to form an alcohol compound comprising a functional group capable of allowing for carbonylation of said alcohol compound, and then reacting said alcohol compound in a carbonylation reaction to form an hydroxycarboxylic acid; and cyclizing the hydroxycarboxylic acid to produce the lactone.
