Abstract

Propylene oxide is prepared by elimination of water from propylene glycol which in turn is obtainable from propylene glycol acetate. The water is eliminated in the gas phase over a solid catalyst which consists of a weakly acidic carrier and an alkaline additive. The process offers a new method of manufacturing propylene oxide.
