摘要：
The present invention-provides a method for preparing a high-purity aqueous quaternary ammonium hydroxide solution, and there is here disclosed this method for preparing the high-purity aqueous quaternary ammonium hydroxide solution which comprises reacting a quaternary ammonium organic acid salt with hydrogen peroxide, oxygen or an oxygen-containing gas in the presence of a platinum group metal catalyst to produce a quaternary ammonium inorganic acid salt, and then electrolyzing this inorganic acid salt by the use of an electrolytic tank having a cation exchange membrane.
