Abstract
A process for preparing conjugated linoleic acid (CLA) or derivatives thereof from ricinoleic acid, lower alkyl esters of ricinoleic acid, or salts thereof. The CLA is formed by reacting a carboxylic acid, or anhydride, anhydride equivalent, or ester thereof with the ricinoleic acid or derivative to form an intermediate having a carboxylic ester at the 12-hydroxy position of the ricinoleic acid or derivative, and reacting the intermediate with a base to form a cis-9, trans-11 conjugated linoleic acid.
