摘要
PURPOSE: To produce an aq. soln. of high-purity quaternary ammonium hydroxide at low cost by electrolyzing a synthesized quaternary ammonium inorg. salt to produce quarternary ammonium hydroxide. ;CONSTITUTION: Reaction of trialkylamine and alkyl ester of carbamic acid is effected in the presence of a polar solvent. Then, water is added to synthesize a quaternary ammonium inorg. salt. The obtd. quaternary ammonium inorg. salt is electrolyzed to produce quarternary ammonium hydroxide. Or, the reaction of trialkylamine and alkyl ester of carbamic acid is effected in the presence of water to synthesize a quaternary ammonium inorg. salt. The obtd. quaternary ammonium inorg. salt is electrolyzed to produce quarternary ammonium hydroxide. Thereby, impurities are prevented from mixing into the aq. soln. of quaternary ammonium hydroxide.;COPYRIGHT: (C)1993,JPO&Japio
