Colorless cubic crystal. Generally speaking, it is white crystal, white multihole , grain, or honeycombing; It's smell-less and a little bitter. Its relative density is 2.15(25 ? ), melting point is 782 ? , boiling point is beyond 1600 ? . With strong hygroscopicity, it is easy to deliquate in the air, but easy to dissolve in water while eliminating plentiful heat. Its water solution is acid deficient. It can dissolve in alcohol, acetone, and acetic acid. Reacting with ammonia or ethanol, it will generate CaCl2 · 8NH3 and CaCl2 · 4C2H5OH complex compound. It crystallizes and separates out six-water substance. Gradually heating up to 30 ? , it will dissolve in its crystal water, continue heating up until desiccation; it turns into two-water substance while the temperature is 200 ? ; while 260 ? , it becomes white multihole anhydrous calcium chloride.
