Method for the production of mono-fatty acid or hydroxy-mono-fatty acid esters of isopropylidene derivatives of a polyglycerol

摘要

The invention relates to a process for the preparation of fatty or hydroxyfatty monoesters of isopropylidene derivatives of a polyglycerol. In this process, a C6-C22-fatty acid or -hydroxyfatty acid is reacted with monoisopropylideneglycerol glycidyl ether or diisopropylidenetriglycerol glycidyl ether in a molar ratio of 0.5:1 to 1:0.5 at temperatures of 373-473 K in the presence of a catalyst and the resulting fatty or hydroxyfatty monoester is, if desired, purified by distillation, fractional distillation and/or ion-exchange.
