Abstract
The process according to the present invention relates to the production of a concentrated solution of sodium hydroxide and chlorine which comprises electrochemical decomposition of a concentrated solution of sodium chloride with a concentration of from 4.3 to 5.3 mol/l at a temperature within the range of from 90.degree. to 108.degree. C. with the degree of decomposition of sodium chloride of 0.9 to 1.0 and the rate of flow of the solution of sodium chloride through a filtering diaphragm of from 3 to 5 ml/hr per 1 A of the electrolysis current, followed by removing the electrolysis products from the process. The process according to the present invention makes it possible to substantially simplify the known procedure of chlorine manufacture, since it ensures obtaining the final commercial product directly in the electrolysis, thus avoiding the stage of evaporation.
