Abstract

A process for producing sodium hypochlorite comprising electrolyzing an aqueous solution of sodium chloride as an electrolyte solution in a non-diaphragm electrolytic cell comprising at least one unit cell in which the ratio of the actual area of the anode to the actual area of the cathode is at least about 1.5: 1. In a preferred embodiment higher concentrations of sodium hypochlorite can be attained by performing the electrolysis while cooling the electrolyte solution to about 50.degree. C. or less.
