ABSTRACT:
Describes a method of electrochemically converting .alpha.-halohydrin, e.g., 1-chloro-2-hydroxypropane and 1,3-dichloro-2-hydroxypropane, to epoxide, e.g., propylene oxide and epichlorohydrin. An aqueous solution of .alpha.-halohydrin is charged to the catholyte compartment of an electrolytic cell, which contains a cathode, hydrogen gas is charged to the anode compartment of the cell, which contains an anode assembly comprising a hydrogen consuming gas diffusion anode fixedly held between a current collecting electrode and an anion exchange membrane. The catholyte and anode compartments of the cell are separated by the anion exchange membrane. An aqueous solution containing epoxide is removed from the catholyte compartment.
