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.
