Abstract
PURPOSE:To produce halogen in the anode and produce alkali metal hydroxide and hydrogen in the cathode, by converting the sulfonic acid radical of the cation exchange film, which has the sulfonic acid radical and a sulfonamide radical on one face and the other respectively, to a weak acid exchange radical having specific % or more with a specific depth. CONSTITUTION:The cation exchange film of the perfluorocarbon copolymer is used where one face and the other consist of the A layer having a sulfonic acid radical as the exchange radical and the B layer having a sulfonamide radical respectively. The sulfonic acid radical of the A layer of this ion exchange film is converted to a weak acid exchange radical such as a carboxyl radical and a phosphoric acid radical in the depth range of 1-100mu by 30% or more thereby forming the A' layer. When this A' layer is directed toward the anode chamber side and alkali metal halogenide is supplied to the anode chamber to perform electrolysis, halogen is produced in the anode chamber and alkali metal hydroxide and hydrogen are produced in the cathode chamber.
