STYRENE PRODUCTION PROCESS Russian patent published in 1998 - IPC

Abstract RU 2106334 C1

FIELD: industrial organic syntheses. SUBSTANCE: styrene is produced via dehydration of methyl phenylcarbinol in the process of combined propylene oxide and styrene production. Invention is distinguished by performing evaporation of liquid raw material and its overheating directly in the reaction zone using heat of steam coming both from contact gas overheater and from steam-overheating furnace. High-boiling substances containing also methyl phenylcarbinol are not preliminarily separated upon evaporation but are decomposed into a series of useful products in the reactor together with bulk of raw material. EFFECT: enhanced process efficiency. 1 dwg, 4 tbl
