Colorless cubic crystals. General industrial products are white or off-white porous blocks or granules, honeycomb. Odorless, slightly bitter. Relative density 2.15. Melting point 782ºC. Boiling point above 1600ºC. Extremely hygroscopic, very easy to deliquesce when exposed to air. Easily soluble in water, while releasing a lot of heat, its aqueous solution is slightly acidic. Soluble in alcohol, acetone, acetic acid. Reacts with ammonia or ethanol to form CaCl2·8NH3 and CaCI2·4C2 Hs OH complexes respectively. The hexahydrate precipitated from the aqueous solution at room temperature is usually dissolved when gradually heated to 30ºC. It dissolves in its own crystal water, continues to lose water when heated, and becomes dihydrate at 200ºC. It becomes white porous anhydrous calcium chloride when heated to 260ºC.
It is mostly used as a desiccant, such as for drying gases such as nitrogen, oxygen, hydrogen, hydrogen chloride, and sulfur dioxide. It is used as a dehydrating agent in the production of alcohols, esters, ethers, and acrylic resins. Calcium chloride aqueous solution is an important refrigerant for refrigerators and ice making. It can accelerate the hardening of concrete and increase the cold resistance of building mortar. It is an excellent building antifreeze agent. It is used as a defogging agent in ports, a road dust collector, and a fabric fire retardant. It is used as a protective agent and refining agent for aluminum and magnesium metallurgy. It is a precipitant for the production of lake pigments. It is used for deinking of waste paper processing. It is a raw material for the production of calcium salts. It is used as a chelating agent and coagulant in the food industry.
