STYRENE-PROPYLENE OXIDE PRODUCTION PROCESS Russian patent published in 2003 - IPC

FIELD: industrial organic synthesis. SUBSTANCE: process comprises: reaction of ethylene with benzene to give ethylbenzene; reaction of ethylbenzene with oxygen or air to give ethylbenzene hydroperoxide; reaction of at least part of the latter with propylene in presence of epoxidation catalyst to yield propylene oxide and 1-phenylethanol; and dehydration of at least part of 1-phenylethanol into styrene in presence of suitable dehydration catalyst. Ethylene and propylene involved in the process are at least partly obtained from emission gas coming from liquid catalytic cracking installation and containing C1 and C2 components. EFFECT: simplified technology. 9 cl, 2 dwg, 1 tbl
