| titleOfInvention | Method of electrochemically producing epoxides |
| abstract | Described is a method of electrochemically converting α-halohydrins, e.g., 1-chloro-2-hydroxypropane and 1,3-dichloro-2-hydroxypropane, to epoxides, e.g., propylene oxide and epichlorohydrin. An electrolytic cell is provided having (1) a catholyte compartment containing a cathode assembly comprising a cathode and a bipolar ion exchange membrane, (2) an anode compartment containing an anode assembly comprising either (a) a hydrogen consuming gas diffusion anode and a current collecting electrode or (b) a hydrogen consuming gas diffusion anode which is fixedly held between a hydraulic barrier and a current collecting electrode, and (3) at least one pair of intermediate compartments separating the catholyte and anode compartments and separated from each other by an anion exchange membrane. The following are introduced into the cell: a first aqueous conductive electrolyte solution into the catholyte compartment; hydrogen gas into the anode compartment; an aqueous solution of α-halohydrin into the first compartment of the pair of intermediate compartments; and a second aqueous conductive electrolyte solution into the second compartment of the pair of intermediate compartments. Direct current is passed through the electrolytic cell, and an aqueous solution comprising epoxide is removed from the first compartment. |
