Process for the production of lithium hypochlorite

摘要

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 DEG to about 20 DEG C. to produce a solution of lithium hypochlorite. The solution is concentrated by evaporation at temperatures in the range of from about 30 DEG to about 60 DEG 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.
