PRODUCT DESCRIPTION
Colorless cubic crystal, white or grayish white, in granular, honeycomb block, spherical, irregular granular and powder forms. Slightly toxic, odorless and slightly bitter. Highly hygroscopic, easily deliquescent when exposed to air. It is easily soluble in water. At 20 ºC, the solubility is 74.5 g/100g water. At the same time, a large amount of heat is released (the dissolution enthalpy of calcium chloride is - 176.2 cal/g). Its aqueous solution is neutral. It is easily soluble in a variety of polar and proton solvents. The solubility (g/100mL solvent) in the following solvents at 20 ºC: methanol: 29.2, absolute ethanol: 25.8, n-propanol: 15.8, n-butanol: 25.0, n-pentanol: 11.5, ethylene glycol: 21.6 (25 ºC), formic acid: 43.1, acetic acid: 15.0 (30 ºC), hydrazine: 16.0. However, in dipolar and low polar solvents, such as ether and tetrahydrofuran, they are only slightly soluble or insoluble. It reacts with ammonia or ethanol to form CaCl2 · 8NH3 and CaCl2 · 4C2H5OH complexes, respectively. Hexahydrate is precipitated from the solution crystallization at low temperature. When it is gradually heated to 30 ºC, it will be dissolved in its own crystal water. After continuous heating, it will gradually lose water. When it is heated to 200 ºC, it will become dihydrate. When it is heated to 260 ºC, it will become white porous anhydrous calcium chloride. During heating and dehydration of hydrated calcium chloride, some hydrolysis reaction occurs, so the product often contains a small amount of CaO impurities.
