Title:
METHOD AND DEVICE FOR PRODUCING QUATERNARY AMMONIUM HYDROXIDE
Document Type and Number:
WIPO Patent Application WO/2021/002235
Kind Code:
A1
Abstract:
A method for producing quaternary ammonium hydroxide in an electrolysis vessel configured so that a negative ion exchange film and a positive ion exchange film are arranged between electrodes, the method being performed by supplying an aqueous solution of quaternary ammonium halide to a chamber partitioned by the negative ion exchange film and the positive ion exchange film and performing electrolysis, wherein the method for producing quaternary ammonium hydroxide is characterized in that electrolysis is performed by using, as the negative ion exchange film, a film in which a proton-transmission-suppressing layer comprising a high-crosslinking resin layer, etc., is formed on a film surface on one side, the film being used in a state in which the surface where the proton-transmission-suppressing layer is formed is arranged so as to face the negative-electrode side.
