Abstract

PURPOSE: To obtain the titled compound in high yield advantageously, by feeding a concentrated olefin chlorohydrin with steam or its mixture with an inert gas in the gaseous state, to a saponification step in a tower, bringing the mixture into the countercurrent contact with an alkaline solution to saponify the olefin chlorohydrin.
CONSTITUTION: An aqueous solution of an olefin chlorohydrin is distilled and concentrated to give a concentrated olefin chlorohydrin, which is in a gaseous state with steam optionally containing an inert gas fed to a saponification step in a tower, brought into the countercurrent contact with an alkaline solution and saponified to give an olefin oxide in high yield. According to the method, a raw material of the olefin chlorohydrin gasified in the distillation and concentration step is usable directly for the saponification step, and a gas blown from the bottom of the tower is used in such a small amount as to strip the olefin oxide dissolved partly in the raw material thermally economically. The dispersed reaction permits the good operability thereof.
