Process for electrolysis of sodium chloride |
| abstract |
A process for the electrolysis of aqueous solutions of sodium chloride in an electrolytic cell separated into an anode chamber and a cathode chamber by a perfluorocarbon copolymer cation exchange membrane having pendant carboxylic acid groups. The process is characterized by reducing the calcium content of the aqueous sodium chloride solution charged into the anode chamber to less than 1 p.p.m. High current efficiencies are obtained utilizing membranes having an ion exchange capacity of carboxylic acid groups of from 0.5 to 2.1 milliequivalents per gram of dry resin. |
