Properties：
Calcium chloride is white porous frit or granule. It is deliquescent.Its melting point is782℃, density is 2.15g/cm3, and its boiling point is higher than 1600℃.It is soluble in water while releasing a lot of heat.It is alsosoluble in ethanol and acetone.
Application：
It can be used as multi-purpose drying agent, such as for drying nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases. It can be used as dehydrating agent in producing alcohol, ester, ether and acrylic resin. Calcium chloride solution is important refrigerant for refrigerator and ice refrigerant. It can accelerate hardening of concrete and increase the tolerance to cold of building mortar. It is an excellent building antifreeze. It can be used as anti-fogging agent of port, road dust and fabric fire retardant. It can be used as protective agent and refining agent of aluminum magnesium metallurgy. It is the precipitant in the production of lake pigments. It can be used to process waste paper deinking. It is raw material to produce calcium.
