Abstract
Mixtures of dimeric and trimeric fatty acid C.sub.1-4 alkyl esters and processes for their preparation comprising either PA1 A) epoxidizing an unsaturated or partially hydrogenated fatty acid glyceride; PA1 B) transesterifying the epoxidized glyceride with a C.sub.1-4 alkanol to obtain epoxidized fatty acid C.sub.1-4 alkyl esters; and PA1 C) ring opening and dimerizing the epoxidized fatty acid C.sub.1-4 alkyl esters; or PA1 A) transesterifying an unsaturated or partially hydrogenated glyceride with a C.sub.1-4 alkanol to obtain olefinically unsaturated fatty acid C.sub.1-4 alkyl esters; PA1 B) epoxidizing the unsaturated fatty acid C.sub.1-4 alkyl esters; and PA1 C) ring opening and dimerizing the epoxidized fatty acid C.sub.1-4 alkyl esters.
