Abstract

PURPOSE:To stably obtain high purity quat. ammonium hydroxide when a salt as starting material is fed to an anode chamber partitioned off by plural cation exchange membranes and electrolysis is carried out, by keeping the salt entering into an intermediate chamber at a prescribed concn. CONSTITUTION:An electrolytic cell is divided into a cathode chamber, an intermediate chamber and an anode chamber by stretching plural cation exchange membranes between the anode and cathode. An aq. soln. of a quat. ammonium salt is fed to the anode chamber, quat. ammonium hydroxide is allowed to exist in the intermediate chamber and an aq. soln. of quat. ammonium hydroxide is drawn out of the cathode chamber. At this time, the quat. ammonium salt entering into the intermediate chamber is kept at 1/10 of the concn. of the quat. ammonium salt in the adjacent anode chamber.
