Abstract
Calcium hypochlorite useful as a commercial sanitizing agent and swimming pool disinfectant is produced by a process wherein calcium hydroxide and organic hypochlorite are reacted in a first reaction zone to produce calcium hypochlorite. The portion of the calcium hydroxide remaining unreacted is recovered along with product calcium hypochlorite in a mixture of solids. In a second reaction zone, an aqueous solution of sodium hydroxide is reacted with an organic hypochlorite to form an aqueous phase containing sodium hypochlorite and an organic phase. The aqueous phase is separated from the organic phase. Chlorine is reacted with the mixture of solids of the first reaction zone and the aqueous phase of the second reaction zone in a third reaction zone to produce an aqueous slurry of calcium hypochlorite particles. The calcium hypochlorite particles are thereafter recovered and dried in granular form.
