ABSTRACT:
The electrolysis of alkali metal chloride solutions in a diaphragm cell having an anode compartment separated from a cathode compartment by a porous perfluorosulfonic acid resin diaphragm is optimized by maintaining the pH of the alkali metal chloride solution in the range of from about 3.0 to about 5.0. In this pH range, highly desirable bulk flow properties are obtained by controlling the dimensional stability of the perfluorosulfonic acid resin.
