Manufacture of quaternary ammonium hydroxide of high purity

Abstract

Abstract PURPOSE:To obtain quat. ammonium hydroxide of high purity by dividing an electrolytic cell into three or more chambers with plural cation exchange membranes, feeding an aqueous soln. of a specified quat. ammonium salt to the anode chamber, and electrolyzing it. CONSTITUTION:An electrolytic cell is divided into one or more intermediate chambers, cathode and anode chambers with plural cation exchange membranes. An aqueous soln. of a quat. ammonium salt represented by the formula (where each of R1-R4 is 1-10C alkyl, 1-10C hydroxyalkyl, 2-10C alkoxyalkyl, aryl or hydroxyaryl, and X is an acid group) is fed to the anode chamber. Water is fed to the cathode chamber, an aqueous soln. of hydroxide corresponding to said quat. ammonium salt is fed to the intermediate chambers, and the aqueous soln. in the anode chamber is electrolyzed.
