Abstract: Disclosed is a granular calcium hypochlorite composition having a calcium hypochlorite content of at least 55 wt.% and composed of particles having an ellipsoidal shape in section, wherein at least 50 wt.% of the ellipsoidal particles have a short diameter of 0.3 - 5 mm, a long diameter of 0.5 - 20 mm, and a long diameter/short diameter ratio larger than 1.5 but not larger than 5. This composition is prepared by a process wherein a wet calcium hypochlorite composition comprising at least 40 wt.% of calcium hypochlorite and 25 - 45 wt.% of water is extruded through a die having an orifice diameter of 0.3 - 5 mm; the extrudate is cut to a length of 0.5 - 20 mm so that the length/orifice diameter ratio is larger than 1.5 but not larger than 5 to form columnar shaped particles; the columnar shaped particles are subjected to rolling granulation; and the resulting granules are dried until the water content is reduced to 4 - 22 wt.%.

Abstract: PURPOSE:To improve the resistance to friction and collapse of the titled compd. higher than the usual compd. and to improve the solubility also, by granulating and forming a mixed crystal composition which is obtained by mixing a proper amt. of a specified coarse calcium hypochlorite dihydrate with the usual plate crystal, etc. CONSTITUTION:The granular calcium hypochlorite is formed by mixing the following two kind crystal of A and B in the wt. ratio of A:B=1:9-9:1. Namely (A) is the coarse calcium hypochlorite dihydrate and/or its anhydrate which is produced by growing a columnar calcium hypochlorite having the ratio between each axis of 0.5 =5mu (c) axis, and then (B) is the plate-crystal of the calcium hypochlorite dihydrate, etc., and/or its anhydrate. The above-mentioned the plate-crystal means a general term of plate crystal, twin crystal (layered crystal) and needle crystal.
