成果简介	NOVELTY - Preparation of hydrated salt of calcium thiosulfate, involves: reacting hydrated calcium chloride (compound (A)) with ammonium thiosulfate (compound (B)) in an aqueous medium at 25-35℃; slowly adding a catalyst into the above slurry at the same temperature, exotherm up to 70-80℃ while addition of catalyst; maintaining the reaction at a temperature of 70- 80℃ until reaction complies; and cooling the reaction to obtain the salt. USE - The process is useful for preparation of hydrated calcium thiosulfate, which is used in agricultural and industrial applications including fertilizers, water treatment, and as stabilizer in photography and textiles. No biological data given. ADVANTAGE - The process is simple and easy step process with no wastage and without bi product. It provides solution with low cost and easily obtained starting material and good yields. It uses less electric energy while during reaction of hydrated salt of the calcium thiosulfate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a hydrated salt of calcium thiosulfate.
