Introduction of calcium chloride

Calcium chloride is an inorganic compound, an element of the composition of chlorine and calcium salts, for typical ionic halides. Calcium chloride is a white character, hard fragments or particles. Bitter, odorless. Calcium chloride to ammonia with outstanding adsorption capacity and low desorption temperature, the ammonia adsorption separation has great application prospects. However, calcium is difficult to form a stable porous material, and ammonia gas contact area is small, and the adsorption and desorption process is easy expansion, agglomeration, thus making it difficult to put into practical application in this regard. Calcium chloride supported on high surface area carrier, can greatly improve the calcium chloride and ammonia gas contact area.

The physical properties of calcium chloride. Calcium chloride is a colorless cubic crystals, white or gray, with granular, honeycomb massive, spherical, irregular granular powder. Non-toxic, odorless, slightly bitter taste. Hygroscopic, easily deliquescence exposed to air. Soluble in water, and release a lot of heat, its solution is slightly alkaline. Soluble in alcohol, acetone, acetic acid. With ammonia or ethanol, respectively, generated CaCl2 · 8NH3 and CaCl2 · 4C2H5OH complexes. Solution crystallization at low temperatures and precipitation for the six water, gradually heated to 30 ℃, then dissolved in its own crystal water, and heating continued gradual evaporation of water, to 200 ℃, into dihydrate, and then heated to 260 ℃ then becomes white porous anhydrous calcium chloride.
