Calcium Chloride Dihydrate soluble in water, and release a lot of heat, the solution was slightly alkaline. Soluble in alcohol, acetone, acetic acid. And the role of ammonia or ethanol, respectively, and generate CaCl28NH3 CaCl24C2H5OH complexes. The solution is precipitated crystalline hexahydrate at a low temperature, gradually heated to 30 , then dissolved in a own crystal water, heating continued gradual water loss, when changed to 200 dihydrate and heated to 260 then becomes white porous anhydrous calcium chloride.

 

Hydrochloric acid and limestone powder reaction. As refrigerants, antifreeze, fire extinguishing agents, for melting ice and snow melting, manufacturing anhydrous calcium chloride, flame retardant cotton fabric, rubber production of condensate agent. Can accelerate hardening and increased tolerance to cold concrete construction mortar, but also used as anti-fogging agent, port and road dust agent. From industrial grade saturated solution of calcium chloride dihydrate, adding bleaching agents, in addition to heavy metal agents, in addition to arsenic solution purification, filtration to remove impurities, liquid cooling and crystallization, solid-liquid separation, drying food grade product can be obtained. Coagulant used cans and soy products, calcium supplements.
