Abstract

PURPOSE: To permit the electrolysis of sodium chloride with a high current coefficient by using a fluorocarbon polymer cation exchange membrane having carboxylic acid and sulfonic acid groups of specific exchange capacity.
CONSTITUTION: As a cation exchange membrane for the electrolysis of sodium chloride in the manufacture of caustic soda, a fluorocarbon polymer exchange membreane with carboxylic acid and sulfonic acid groups of a 0.5W4.0 milli-equivalent/g of dry resin exchange capacity is used. The use of the cation exchange membrane as a diaphragm for the electrolysis of sodium chloride prevents the back diffusion of OH ion from the cathode compartment to the anode compartment and hence assures the manufacture of enriched, high purity caustic soda due to the high electric conductivity of sulfonic acid group and the performance of highly economical electrolysis.
