  • General Description
    • White to off-white solid. Sinks and mixes with water.

  • Air & Water Reactions
    • Deliquescent. Water soluble. Adding Calcium chloride to hot water caused violent boiling, [MCA Case History No. 69].

  • Reactivity Profile

    Bromine trifluoride rapidly attacks the following salts: barium chloride, cadmium chloride, Calcium chloride, cesium chloride, lithium chloride, silver chloride, rubidium chloride, potassium bromide, potassium chloride, potassium iodide, rhodium tetrabromide, sodium bromide, sodium chloride, and sodium iodide [Mellor 2 Supp. 1:164, 165 1956]. Long term exposure of Calcium chloride solution upon a zinc coated galvanized iron vessel caused slow evolution of hydrogen which ignited and exploded [Bretherick, 5th Ed., 1995].

  • Synthesis
    • 1. Calcium chloride dihydrate method dehydrates and dries edible calcium chloride dihydrate to obtain edible anhydrous calcium chloride at 200~300℃. Its reaction equation: CaCl22H2O [260℃] → CaCl2 + 2H2O For spray drying dehydration method, refined neutral calcium chloride solution that has been removed arsenic and heavy metals sprays mist through a nozzle above the spray drying tower, and contacts with 300℃ hot air countercurrent to dry and dehydrate. Then powdery anhydrous chloride calcium is obtained, and edible anhydrous calcium chloride is prepared. 2. Lime milk is added into the mother liquor to prepare sodium carbonate by ammonia-soda process to obtain aqueous solution. Then it can be obtained by evaporation, concentration, cooling, curing. It can be obtained by reaction of calcium carbonate and hydrochloric acid. It can be obtained by the rectification of by-products in the production of sodium hypochlorit.

  • Usage
    • 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.

  • Health Hazard

    Inhalation causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes (particularly by dust) causes irritation and possible transient corneal injury. Contact of solid with dry skin causes mild irritation; strong solutions can cause marked irritation, even a superficial burn.
