A process can prepare a compound having the formula;wherein 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 including 2, 4 or 6 branched acyl groupswherein at least one of R1, R2 and R3 is selected from short acyl groups of the formula;wherein q is from 0 to 4. |

1. A process for the preparation of a compound having the formula wherein 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 including 2, 4 or 6 branched acyl groups wherein at least one of R1, R2 and R3 is 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 wherein R1, R2 and R3 are independently selected from
(a) hydrogen,(b) a C10-C22 unsaturated long acyl group having one, two or three carbon-carbon double bonds; and(c) short acyl groups of the formula wherein q is from 0 to 4 wherein at least one of R1, R2 and R3 is an unsaturated long acyl group; and (2) if at least one of R1, R2 and R3 is hydrogen, optionally acylating the compound; and (3a) (i) hydroxylating the C10-C22 unsaturated long acyl group, and (ii) acylating the hydroxylated long acyl group with a carboxylic acid of the formula wherein p is from 0 to 4 to provide a branched long acyl group including 2, 4 or 6 branched acyl groups; or (3b) reacting the unsaturated long acyl group with a carboxylic acid of the formula wherein p is from 0 to 4 to provide a branched long acyl group including 2, 4 or 6 branched acyl groups. |
