Dimer and trimer acid esters from epoxidized compounds and methods for their preparation

摘要

Mixtures of dimeric and trimeric fatty acid C1-4 alkyl esters and processes for their preparation comprising eitherA) epoxidizing an unsaturated or partially hydrogenated fatty acid glyceride;B) transesterifying the epoxidized glyceride with a C1-4 alkanol to obtain epoxidized fatty acid C1-4 alkyl esters; andC) ring opening and dimerizing the epoxidized fatty acid C1-4 alkyl esters; orA) transesterifying an unsaturated or partially hydrogenated glyceride with a C1-4 alkanol to obtain olefinically unsaturated fatty acid C1-4 alkyl esters;B) epoxidizing the unsaturated fatty acid C1-4 alkyl esters; andC) ring opening and dimerizing the epoxidized fatty acid C1-4 alkyl esters.
