Abstract

Propylene oxide is prepared by elimination of acetic acid from propylene glycol monoacetates in the presence of a base. In contrast to the conventional elimination of acetic acid in the gas phase, the present reaction is carried out in the liquid phase in a high-boiling solvent. Because of the smaller reaction space required, the reaction in the liquid phase is simpler.
