Description

Product Name: Calcium chloride

Model-4: Powder

Molecular formula: CaCl2

Molecular weight: 110.99

Physical and chemical character: Colorless cubic crystal. It is a white crystal in state of multiple-hole, grain or honeycomb, smell less and taste bitter. The relative density is 2.15 at 25℃, 782℃ melting degree, beyond 1600℃ boiling degree. Powerful hygroscopic, easy to deliquesce in the air, dissolvable in water while eliminating plentiful heat. Its aqueous solution is in the state of slight acidity. It is dissolvable in alcohol, acetone and acetic acid. Reacting with ammonia or ethanol to generate CaCl2 · 8NH3 and CaCl2 · 4C2H5OH complex compounds. Its aqueous solution separates out six-water substance under normal temperature, gradually heating up to 30℃ , it will dissolve in its crystal water, continue heating up till desiccation, it turns into two-water substance when the temperature reaching to 200 ℃, up to 260 ℃, it turns into white multiple-hole anhydrous calcium chlorid.
