Process for the preparation of styrene

摘要

The invention relates to a process for the preparation of styrene comprising the gas phase dehydration of 1-phenylethanol at elevated temperature in the presence of a dehydration catalyst in which the dehydration catalyst is a shaped alumina catalyst particles having a surface area (BET) of from 80 to 140 m<2>/g and a pore volume (Hg) of more than 0.65 ml/g.
