Abstract

PURPOSE:To prevent the penetration of impurities and to enhance the electrolytic efficiency by feeding an aqueous alkali chloride soln. to the anode chambers of an electrolytic cell divided into anode and cathode chambers by cation exchange membranes under specified conditions and partially circulating a liq. catholyte. CONSTITUTION:An aqueous alkali chloride soln. is fed to the anode chambers of an electrolytic cell divided into anode and cathode chambers by cation exchange membrances, and it is electrolyzed. This soln. is well freed of impurities, kept at 6-12pH, fed by a one-pass system, and maintained at >=150g/l concn. in the anode chambers. An aqueous alkali hydroxide soln. obtd. by the electrolysis in the cathode chambers is partially circulated to make the concn. of the liq. catholyte in the many cathode chambers uniform, and the temp. of the cell is also made uniform.
