Abstract
A novel process for the production of granular calcium hypochlorite compositions is provided which comprises reacting neutral calcium hypochlorite with an alkaline solution comprised of an alkali metal hypochlorite and an alkali metal hydroxide. The reaction produces a slurry from which a wet cake comprised of neutral calcium hypochlorite and a residual amount of hemibasic calcium hypochlorite is recovered and dried. During the drying process in which granular calcium hypochlorite compositions are obtained, there is a substantial reduction in the loss of available chlorine from the product.
