Abstract

Improvements introduced in a procedure for the electrolysis of an aqueous solution of sodium chloride in an electrolytic cell, whose anodic and cathodic compartments are separated by a cationic, electrolytically conductive and hydraulically waterproof membrane, characterized by improvements consisting essentially of establishing an initial concentration of sodium hydroxide in the catholyte between 31 and 43% and maintaining said concentration of sodium hydroxide within the aforementioned range by controlling the average concentration of sodium chloride in the anolyte within the range of 120 to 250g/liter, with the only source of water is the transported catolith, through said membrane.
