Abstract

A process for the production of epichlorohydrin in the form of a mixture thereof with water vapour comprises treating with steam an aqueous reaction medium which is provided by mixing an inorganic alkali hydroxide, water and dichlorohydrin, said reaction medium immediately prior to said steam treatment being at a temperature of below 55 DEG C., thereby stripping the epichlorohydrin, produced in the reaction medium, from said reaction medium as a gaseous mixture comprising epichlorohydrin and water vapour, the temperature of said gaseous mixture being stripped from the reaction medium being above the normal boiling point of the water-epichlorohydrin azeotrope, said gaseous mixture having a water vapour content which is at least 50% by weight of the water vapour and epichlorohydrin, the water vapour content being determined by the amount of steam admitted. The gaseous mixture of epichlorohydrin and water vapour which may also contain some dichlorohydrin is preferably condensed, phase separated into an organic phase and an aqueous phase containing dichlorohydrin, and the aqueous phase recycled as part of the dichlorohydrin source.
