Abstract
PURPOSE: To manufacture the titled compound useful as high test hypochlorite of high quality with a small amount of seed crystals by adding prismatic crystals of calcium hypochlorite dihydrate as seed crystals and chlorinating semibasic calcium hypochlorite.
CONSTITUTION: A suspension of calcium hydroxide and/or dibasic calcium hypochlorite is chlorinated to crystallize semibasic calcium hypochlorite, which is then chlorinated to crystallize calcium hypochlorite dihydrate. At this time, by adding prismatic crystals of calcium hypochlorite dihydrate as seed crystals, coarse calcium hypochlorite dihydrate is obtd. The prismatic crystals have abnormally developed (c) axis of ≥5μ, (a) and (b) axes whose growth has been extremely controlled, and the following axial ratios: 0.5≤ b/a ≤2.0 and c/a ≥1.5.
