Abstract
PURPOSE:To prevent the damage of a cation exchange membrane and to operate an electrolytic cell having anodic and cathodic chambers divided with the membrane at a low voltage by putting spacers each having a specified opening rate between the membrane and an anode and between the membrane and a cathode at vapor-liq. mixed phase parts formed at an upper part of the cell with gases generated from the anode and the cathode. CONSTITUTION:In an electrolytic cell having anodic and cathodic chambers divided with a cation exchange membrane an aqueous soln. of alkali chloride is electrolyzed to manufacture caustic alkali. At this time, gases are generated from an anode and a cathode to form vapor-liq. mixed phase parts at an upper part of the cell. Spacers each having 10-90% opening rate are put between the membrane and the anode and between the membrane and the cathode at the mixed phase parts. Each of the spacers is made of asbestos filament, glass fiber, polyvinyl chloride or other material with resistance to the electrolytic soln. and chlorine.
