Method for electrolyzing alkali metal halide aqueous solution

摘要

This invention relates to a method for electrolyzing an alkali metal halide aqueous solution in a three-chamber horizontal type electrolytic cell which comprises a top cathode chamber bounded by a cation exchange membrane, a middle chamber, and a bottom anode chamber bounded by a diaphragm. Halogen gas and dilute alkali metal halide solution are taken out of the anode chamber in such a manner as to make the anode chamber work as a gas chamber.
