ABSTRACT:
Disclosed is an electrolytic process of an aqueous alkali metal chloride solution using a cation exchange membrane as a separator of an electrolytic cell, which comprises effecting the electrolysis while utilizing impact resilience of springs positioned at anodes and exerting positive pressure on a cathode compartment of the cell. Not only is stable operation at low cell voltage for a prolonged period of time enabled, but also high purity alkali metal hydroxide containing a reduced amount of sodium chloride is produced.
