Process for the preparation of styrene and propylene oxide |
摘要 |
A process for the joint preparation of styrene and propylene oxide comprising the steps of: (a) reacting ethane 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 with propene in the presence of an epoxidation catalyst to form propylene oxide and 1-phenyl ethanol, and (d) dehydrating at least part of the 1-phenyl ethanol obtained 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.
