Abstract:
A process for the joint preparation of styrene and propylene oxide comprising the steps of:(a) reacting ethene and benzene to form ethylbenzene, (b) reacting ethylbenzene with oxygen or air to form ethylbenzene hydroperoxide, (c) reacting at least part of the ethylbenzene hydroperoxide obtained from (b) with propene in the presence of an epoxidation catalyst to form propylene oxide and 1-phenyl ethanol, and (d) dehydrating at least a part of the 1-phenyl ethanol obtained from (c) into styrene in the presence of a suitable dehydration catalyst, wherein the ethene used in step (a) and the propene used in step (c) are at least partly provided by a fluid catalytic cracking unit.
