A process for preparing chlorinated lime solid having an available chlorine content in the range of about 30 to about 50 weight percent by contacting a chlorine source, e.g., liquid chlorine, with a basic calcium-containing substance, e.g., hydrated lime, in the presence of water or aqueous calcium chlorine at a pH to produce an aqueous slurry having available chlorine content in the range of about 13 to 17 weight percent and a pH in the range of about 10.6 to 10.9 and containing an aqueous solution and a chlorinated lime precipitate combined with separating said slurry into an aqueous solution and a chlorinated lime precipitate having less than about 40 to 50 percent water combined with drying said chlorinated lime precipitate to produce chlorinated lime solid having the desired available chlorine content is disclosed.
