Process for production of quaternary ammonium hydroxides
A process for producing quaternary salts of high purity is disclosed, comprising reacting a tertiary amine or phosphine with a carbonic acid diester to form a corresponding quaternary carbonate and further mixing it with an acid to perform decarboxylation. The quaternary salts thus obtained are useful compounds which can be used in wide fields as various catalysts, electrolytes, additives, medicaments, etc.

A process for production of high purity quaternary ammonium hydroxides, comprising electrolyzing quaternary ammonium hydrogencarbonates represented by the general formula:
(wherein the symbols are as defined in the appended claims) in an electrolytic cell comprising an anode compartment and a cathode compartment defined by a cation exchange membrane. In accordance with this process, high purity quaternary ammonium hydroxides can be produced with high electrolytic efficiency and further without causing corrosion of equipment. Since the quaternary ammonium hydroxides produced by the present invention are of high purity, they can be effectively used as, for example, cleaners, etchants or developers for wafers in the production of IC and LSI in the field of electronics and semiconductors.
