C-I-L 714 ABSTRACT A process for the production of calcium hyopchlorite from calcium hydroxide and chlorine in the presence of sodium hydroxide and dibasic calcium hypochlorite wherein the dibasic calcium hypochlorite is prepared from the calcium hypochlorite containing primary mother liquor and recycled evaporator mother liquor, and calcium hydroxide. The process provides improved quality calcium hypochlorite products and sodium chloride by-product. It also avoids the separation of co-crystallized calcium hypochlorite and sodium chloride and the precipitation and separation of calcium hydroxide as part of the recovery process.
