Electrolytic cell for producing alkali metal hypochlorites

摘要

A process for producing an alkali metal hypochlorite which comprises electrolyzing an aqueous solution of an alkali metal chloride in an electrolytic cell including a plurality of unit cells, each equipped with at least one anode and at least one cathode, in which the unit cells are arranged in series via partitioning plates, wherein hydrogen gas generated at the cathode in each unit cell is passed out of each unit cell such that the hydrogen gas does not contact the cathode portion that takes part in electrolysis in the next adjacent unit cell and an electrolytic cell therefor.
