VERFAHREN ZUR HERSTELLUNG VON ALKYLESTERN VON 3,4-EPOXYBUTTERSAEURE.

摘要

Method for the preparation of an alkyl ester of 3,4-epoxybutyric acid, of formula: R being a linear or branched alkyl group, containing from 4 to 10 C atoms, wherein the corresponding vinylacetate is catalytically oxidized in a biphasic liquid system comprising: a) an aqueous phase, containing H2O2 as oxidizing agent; b) an organic phase, containing said vinylacetate and a catalyst selected from peroxidic compounds of formula: (R1 R2 R3 R4 N)3 PW4O24 as well as, optionally, a solvent immiscible with the aqueous phase.
