Abstract
The alkali metal chlorates (or perchlorates) are produced by electrolyzing the anolyte contained in the anode compartment of an electrolytic cell compartmentalized by means of a selectively permeable cationic membrane into said anode compartment and a cathode compartment, said anolyte having a pH ranging from about 6.2 to about 6.6 and comprising an aqueous solution of from about 100 g/l to about 200 g/l of the corresponding alkali metal chloride (or chlorate) and such amount of the desired alkali metal chlorate (or perchlorate) that the final product chlorate (or perchlorate) may be directly crystallized from the electrolyzed anolyte, and said cathode compartment containing a catholyte comprising an aqueous solution of the corresponding alkali metal hydroxide and wherein hydrogen gas is evolved.
