Colorless cubic crystal, white or off-white, granular, honeycomb block, spheroid, irregular granular, powdered. Slightly toxic, odorless, slightly bitter taste. Extremely hygroscopic and easily deliqued when exposed to air. It is easily soluble in water, and the solubility is 74.5g /100g water at 20ºC, while releasing a large amount of heat (the dissolution enthalpy of calcium chloride is -176.2cal/g), and its aqueous solution is slightly acidic. Soluble in a variety of polar, protic solvents, solubility at 20ºC in the following solvents (g/100mL solvent): methanol :29.2, anhydrous ethanol :25.8, n-propanol :15.8, n-butanol :25.0, n-amyl alcohol :11.5, ethylene glycol :21.6(25ºC), formic acid :43.1, acetic acid :15.0(30ºC), Hydrazine :16.0. However, in dipolar solvents and low polar solvents, such as ether, tetrahydrofuran, etc., it is only slightly soluble or insoluble. Reacting with ammonia or alcohol, CaCl2·8NH3 and CaCl2·4C2H5OH complexes are formed, respectively. At low temperature, the solution crystallizes and precipitates as a hexahydrate, which is gradually dissolved in its own crystalline water when heated to 30 ° C, and gradually loses water when heated to 200 ° C, and becomes a dihydrate when heated to 260 ° C, which becomes a white porous anhydrous calcium chloride. Some hydrolysis reactions occur in the process of heating dehydration of hydrated calcium chloride, so the products often contain a small amount of CaO impurities.
1, used as a multi-purpose desiccant, such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases drying. Used as dehydrating agent in the production of alcohols, esters, ethers and acrylic resins. Calcium chloride aqueous solution is an important refrigerant for chillers and ice making, which can accelerate the hardening of concrete and increase the cold resistance of building mortar, and is an excellent building antifreeze. Used as port fogging agent and road dust collector, fabric fire retardant. Used as a protective agent and refining agent for aluminum and magnesium metallurgy. It is a precipitating agent for the production of lake pigments. Used for deinking waste paper processing. It is a raw material for the production of calcium salts.
