ABSTRACT:
Both crystals and solutions containing alkali metal chlorates are continuously prepared by chemical followed by electrochemical steps whereby a reaction product comprising alkali metal chloride, chlorate and hypochlorite is prepared by mixing and chemically reacting an alkali metal hydroxide solution with chlorine under conditions which favor and promote the conversion of the alkali metal hypochlorite formed during the initial chemical reaction to alkali metal chlorate without the need for further dilution and acidification of the mixture during the chemical reaction. A portion of the chemical product is electrolyzed in an electrolytic cell to increase the concentration of chlorate for making sodium chlorate crystals and/or R-2 solution, and a portion of the chemical product is also recycled for further use in the chemical reaction with chlorine and alkali metal hydroxide for the continuous preparation of alkali metal chlorate.
