ABSTRACT:
A process for producing lithium hypochlorite comprises admixing an aqueous hypochlorous acid solution having a concentration of 35 percent of greater by weight of HOCl with an aqueous slurry of lithium hydroxide at a temperature in the range of from about 0.degree. to about 20.degree. C. to produce a solution of lithium hypochlorite. The solution is concentrated by evaporation at temperatures in the range of from about 30.degree. to about 60.degree. C. and at subatmospheric pressures to form a paste of lithium hypochlorite. After separating the paste into a cake of lithium hypochlorite and a mother liquor, a potassium compound is admixed with the mother liquor. The process produces a highly pure solid lithium hypochlorite product having a concentration of at least 80 percent available chlorine.
