ABSTRACT:
Process for the electrolysis of an aqueous alkali metal chloride solution using a cation exchange membrane, wherein the gas-liquid interface, at which halogen gas is separated, is maintained larger than the sum total of the cross section area of the unit anode chambers opposing to cathodes, and further, higher than the upper end of the cation exchange membrane. The invention has numerous advantages including substantial absence of halogen gas, operation at a low voltage, a high pure product, simplification of operation control and the like.
