Abstract

Improvements introduced in a co-production method of styrene and a lower alkylene oxide, in which a stream of ethylbenzene is oxidized to ethylbenzene hydroperoxide, said ethylbenzene hydroperoxide is used to react with an olefin to prepare a stream of an oxide of lower alkylene, a stream containing methylbenzylalcohol is passed through a dehydration zone to prepare steam and styrene, a stream of acetophenone containing several impurities constitutes a by-product, a stream containing methylbenzylalcohol is prepared by hydrogenation of a stream containing acetophenone together with hydrogen on a layer of catalyst particles consisting of zinc oxide which supports catalytic amounts of copper at a temperature above room temperature and a pressure above atmospheric pressure, said styrene and said lower alkylene oxide are recovered separately as co-products of the operation.
