石嘴山Calcium chloride

CAS NO:10043-52-4英文名称：Calcium chloride(anhydrous calcium chloride）

分子式：CaCl2分子量：110.98

Melting point: 772℃ (otherwise known as 782℃)

Boiling point: above 1600℃

Relative density: 2.15 relative density: 2.15(25℃)

Characters: colorless cubic crystal, white or off-white, granular, honeycomb, spherical, irregular granular, powdery. Non-toxic, odorless, slightly bitter taste. Highly hygroscopicity, easy deliquescence when exposed to air. Insoluble in organic solvents, aqueous solution is weakly alkaline, 10% aqueous solution, PH value is 7-9, soluble in water (give off a lot of heat), ethanol, acetone, acetic acid, formic acid, hydrazine, pyridine and acetamide, insoluble in ether. The solubility of calcium chloride in water is very high. It can dissolve 59.5 grams of calcium chloride in 100 grams of water at 0℃, 74g in 20℃, and 159 grams in 100℃. The solution crystallizes at low temperature and precipitates into hexahydrate, which is gradually dissolved in its own crystalline water when heated to 30℃, then gradually loses water when heated to 200℃, then becomes dihydrate when reheated to 260℃ and becomes white porous anhydrous calcium chloride.

USES:

Can do desiccant (such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gas drying,) de-icing agent, solidifying agent, inorganic industry used for manufacturing metal calcium, barium chloride, a variety of calcium salt (such as calcium phosphate) raw materials. The construction industry is used as antifreeze to accelerate the hardening of concrete and increase the cold resistance of building mortar. Calcium chloride solution is an important refrigerant in refrigeration industry. Microbial industry is used as a medium for haploid breeding. In addition, it is also used as a fire retardant for fabrics, an antifogging agent for seaports, a dust collector for pavements, and a food preservative. At the same time, it is also used in petroleum exploitation, oil field cementing, oil field exploration, artificial rainfall, chemical industry, mining, construction, transportation metallurgy, medicine, electronics industry, food storage and other industries.

Packing: plastic inside and woven outside, net weight 25, 50 and 1000kg per bag, stored in a ventilated and dry place.
