Title:
MANUFACTURE OF PHENYLPROPANONE
Document Type and Number:
Japanese Patent JPS62142136
Kind Code:
A
Abstract:
Process for the preparation of phenylpropanones having formula:R and/or R1, each other equal or different, being C1-C4 alkyl groups, optionally forming part of an alicyclic or heterocyclic ring, wherein the corresponding allylbenzenes are catalytically epoxidated by means of H202, in a biphase system comprising an aqueous phase containing H202, an organic phase containing said allylbenzenes, a solvent immiscible in said aqueous phase and a catalyst having formula Q3XW4O24 (Q being a quaternary cation, containing hydroxarbylic groups having on the whole from 20 to 70 C atoms, and X being P or As) and wherein the thus obtained epoxides are isomerized by heating at 90°-150°C, in the presence of catalytic amounts of Lil.
