Anhydrous Calcium Chloride

Calcium chloride is a colorless cubic crystal, white or gray, granular, honeycomb lumps, spherical, irregular granular, powdery. Micro-toxic, odorless, slightly bitter taste. Extremely hygroscopic, extremely deliquescent when exposed to the air. Soluble in water, at the same time release a lot of heat (CaCl2 enthalpy of -176.2cal g), the aqueous solution was slightly acidic. Soluble alcohol, acetone, acetic acid. And ammonia or ethanol role, respectively, generated CaCl2 · 8NH3 and CaCl2 · 4C2H5OH complex. Crystallization of the solution at low temperatures and precipitation of hexahydrate, gradually heated to 30 ℃ when it is dissolved in its own crystal water, continue to gradually dehydration heating, to 200 ℃ into dihydrate, and then heated to 260 ℃ becomes White porous anhydrous calcium chloride Detailed introduction:  Molecular Formula: CaCl2 Molecular Weight:: 219.08 Cas No.: 10043-52-4 HS Code: 28272000 Standard: GBT23941-2009  Calcium Chloride Dihydrate Appearance White Flakes or Powder Assay as CaCl2 7477% min.
