Abstract

PURPOSE: To minimize the increase in bath voltage as well as obtain high concentrations of NaOH with high current efficiency by electrolyzing saline water by turning the specific side of a parallelized two-layer fluorine-containing cation exchange membrane with different side chains to the anode side.
CONSTITUTION: A fluorine-containing exchange membrane, consisting of the two layers, one having the side chain represented by the formula I (M is H, an alkali metal, or ammonium and n is integer of 2W5) and the other having any one or both side chains represented by the formula II (M and n are the same as in the formula I, R is any one of groups of the formula III, IV, V, VI, VII, and VIII, m is 2W10, and l is 1W10) and the formula IX (M, n, and R are the same as in the foregoing formulas), is used. When the electrolysis of saline water is made by turning the layer having the side chain of the formula I of the exchange membrane to the side of anode, approx. 36% NaOH can be obtained and a long-term operation can be stably performed at a bath voltage of approx. 3.8V and a current efficiency of approx. 94%, for example.
