Abstract
An improved procedure for recovering lime from an aqueous calcium hypochlorite solution, in which the lime is precipitated in a reaction zone by the reaction of an alkali metal hydroxide with said aqueous solution, and recovering the produced solid lime particles, wherein the improvement comprises reacting said alkali metal hydroxide with said aqueous solution in sufficient proportion to maintain the pH in the range from about 11 to about 13.5, whereby a mixture of crystalline particles of calcium hypochlorite is formed. semi-basic and lime.
