PROCESS FOR PREPARING STYRENE Russian patent published in 1997 - IPC

Abstract RU 2083543 C1

FIELD: petrochemical industry, more particularly combined preparation of propylene oxide and styrene. SUBSTANCE: methylphenylcarbinol is subjected to vapor phase dehydration in two-step adiabatic reactor in the presence of water containing gas introduced into reaction zone in at least two streams at weight ratio in the steps of 8:1- 3 and methylphenyl carbinol to steam to hydrogen ratio of 1:0.8-1.0:0.0004-0.04. EFFECT: higher efficiency. 1 dwg, 1 tbl
