ACID CATALYZED OLIGOMERIZATION OF ALKYL ESTERS AND CARBOXYLIC ACIDS

摘要

The oligomerization of certain carboxylic acids and alkyl esters derived from natural oils is disclosed. This includes the oligomerization of C10-17 unsaturated carboxylic acids such as 9-decenoic acid, where the oligomerization yields a mixture of mono-, di- and tri-carboxylic acids. This also includes the oligomerization of certain alkyl esters, including the oligomerization of C10-17 unsaturated alkyl esters such as methyl 9-decenoate (9-DAME), where the oligomerization yields a mixture of mono-, di- and tri-carboxylic acid esters. Various end use applications for the oligomerized carboxylic acids and oligomerized alkyl esters are also disclosed.

1. A composition comprising a crude mixture of oligomers of C10-C17 alkyl esters, wherein the crude mixture comprises:
(a) from 18% to 81% as measured by GC/MS percent area, of monomers of C10-C17 alkyl esters, (b) from 14% to 45% as measured by GC/MS percent area, of dimers of C10-C17 alkyl esters, (c) from 0% to 18% as measured by GC/MS percent area, of trimers and/or higher unit oligomers of C10-C17 alkyl esters, and (d) from 5% to 30% as measured by GC/MS percent area, of byproducts or lactone.
