Calcium Chloride Dihydrate

CAS：10035-04-8

Molecular formula：CaCl2H4O2

Molecular weight：147.01

Physicochemical properties: colorless crystal. Generally, the commodity is white, gray white or slightly yellow crystal. It is bitter and astringent and has strong deliquescence. The relative density is 1.835. It is easily soluble in water. Its aqueous solution is neutral or slightly alkaline and corrosive. Soluble in alcohol, insoluble in ether. When heated to 260 ℃, dehydration becomes anhydrous. Other chemical properties are similar to anhydrous calcium chloride.

Usage: calcium chloride dihydrate is most widely used in the market as a snow melting agent.

Properties

It is used as refrigerant (such as frozen brine for refrigerator, frozen brine for ice making and ice stick), antifreeze, automobile antifreeze and fire extinguishing agent. Flame retardant for melting ice and snow, finishing and finishing of cotton fabrics. Used as adhesive and wood preservative. It is the raw material for manufacturing anhydrous calcium chloride. It is used in wall painting and plastering to increase the setting capacity. Rubber production is used as a coagulant. Mixed starch paste is used as sizing agent. It is also used in nonferrous metal smelting. Used as medicine.
