Title:
METHOD OF PREPARING ETHYLBENZENE HYDROPEROXIDE BY LIQUID-PHASE PEROXIDATION OF ETHYLBENZENE AND PREPARATION METHOD OF PROPYLENE OXIDE
Document Type and Number:
WIPO Patent Application WO/2019/119489
Kind Code:
A1
Abstract:
The present invention relates to a method of preparing ethylbenzene hydroperoxide by liquid-phase peroxidation of ethylbenzene and a preparation method of propylene oxide. By adding a small amount of an organic basic substance, the peroxidation between ethylbenzene and an oxygen-containing gas is facilitated. The method can effectively increase the selectivity of a target product, and the added organic basic substance does not affect the activity of a subsequent epoxidation catalyst.
