Industrial Calcium Chloride with CAS No. 7774-34-7
Calcium chloride, a salt composed of chlorine and calcium, chemical formula CaCl2. Slightly bitter, tasteless. It is a typical ionic halide that is white, hard, brittle, or particulate at room temperature. Its common applications include brines, road melters, and desiccants used in refrigeration equipment. Because it absorbs water in the air and deliquesces, anhydrous calcium chloride must be stored in sealed containers. Calcium chloride and its hydrates and solutions have important application values in many aspects such as food manufacturing, building materials, medicine and biology. Calcium chloride has prominent adsorption capacity for ammonia and low desorption temperature, and has a great application prospect in the adsorption and separation of ammonia. However, since calcium chloride does not easily form a stable porous material, the contact area with ammonia gas is small, and it easily expands and agglomerates during adsorption and desorption, thus making it difficult to put it into practical use in this respect. When calcium chloride is supported on a high surface support, the contact area between calcium chloride and ammonia gas can be greatly increased. Related studies have shown that composite adsorbents prepared by loading calcium chloride on molecular sieves have better adsorption performance and stability than single adsorbents.
CAS No. : 7774-34-7
EINECS No. : 233-140-8
Melting Point: 30 °C
Density: 1.71 g/mL at 25 °C(lit.)
Solubility: H2O: 1 M at 20 °C, clear, colorless
PH: 5.0-7.0 (25℃, 1M in H2O)
Solubility in Water: 5360 g/L (20 ºC)
Achromatic cubic crystals, white or gray, granular, honeycomb block, spherical, irregular granular, powder. Micro-toxic, odorless, slightly bitter taste. Very hygroscopic, easily deliquescent when exposed to air. Soluble in water, while releasing a lot of heat (calcium chloride dissolved enthalpy -176.2cal / g), the aqueous solution was slightly acidic. Soluble in alcohol, acetone, acetic acid. With ammonia or ethanol, CaCl2 · 8NH3 and CaCl2 · 4C2H5OH complexes are generated. When the solution is crystallized at a low temperature, hexahydrate is precipitated. When it is gradually heated to 30°C, it dissolves in its own crystal water and gradually loses moisture when heated. When it is heated to 200°C, it becomes a dihydrate, and when it is heated to 260°C, it becomes White porous anhydrous calcium chloride.
