Calcium dichloride is a white or gray chemical, often in granular form, and is most commonly used in the market as a snowmelt agent.
Physical and chemical properties
Appearance: colorless cubic crystal, white or off-white, granular, honeycomb [block, round ball, irregular granular, powder. Non-toxic, odorless, slightly bitter taste.
Relative density: 2.15(25ºC)
Melting point: 782 ºC
Boiling point: above 1600ºC.
Highly hygroscopicity, easy deliquescence when exposed to air.
Solubility: soluble in water, giving off a lot of heat at the same time, the aqueous solution is slightly alkaline.Soluble in alcohol, acetone, acetic acid.CaCl28NH3 and CaCl24C2H5OH complexes were generated by interaction with ammonia or ethanol, respectively.The solution crystallizes at low temperature and precipitates into hexahydrate, which is gradually dissolved in its own crystalline water when heated to 30ºC, then gradually loses water when heated to 200ºC, then becomes dihydrate when reheated to 260ºC and becomes white porous anhydrous calcium chloride.
Also known as ice calcium.Colorless crystal.General goods are white, gray or slightly yellow flake or block solid taste bitter and acerbity.Density 1.85g/cm3(20 °C).Soluble in water, soluble in alcohol, insoluble in ether.The aqueous solution is neutral or slightly alkaline.Corrosive.When heated to 260ºC, it dehydrates into anhydrous substance.Strong deliquescence.The distilled waste liquid (containing 100g/L calcium chloride) in the production of soda soda by ammonia-alkali method is purified, clarified, evaporated and separated from sodium chloride. The mother liquor is clarified and further concentrated. When the content of calcium chloride reaches 70%, it is cooled.It can also be prepared by reaction of hydrochloric acid and limestone powder.Used as refrigerant, antifreeze, extinguishing agent, melting ice and snow, manufacturing anhydrous calcium chloride, flame retardant for cotton fabric, condensate for rubber production.It can accelerate the hardening of concrete and increase the cold resistance of building mortar. It is also used as antifogging agent for port and dust collector for road surface.The solution is purified by adding decolorizer, removing heavy metal agent and arsenic agent, filtering and removing impurities, cooling and crystallization of filtrate, solid-liquid separation and drying to produce edible products.Used as a solidifying agent and calcium fortifier for canned and soybean products.

Purpose 1: used as refrigerant, also used in food processing, pharmacy, etc
Application: used as calcium fortifier, chelating agent, curing agent and refrigerant in food industry.
Use 3: make feed calcium supplement.
Application 4: as a solidifying agent, it can be used in soybean products according to production requirements.
Purpose 5: used as refrigerant (such as frozen brine for freezer, frozen brine for ice making and Popsicle making), 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 producing anhydrous calcium chloride.Used in wall painting and plastering to increase condensation capacity.Rubber is produced as a condensate.Mixed starch paste is used as gluing agent.It is also used in the smelting of non-ferrous metals.Used as medicine.
Application: oxygen and sulfur absorbent.Food protectants.Sizing agent.Water purifier.Antifreeze.
Storage and transport properties
Store in a cool, dry, well-ventilated place away from incompatible substances.Keep container closed.Calcium chloride in block dihydrate is packed in medium open iron drum with net weight of 200kg per drum.Flake calcium chloride dihydrate is packed in woven bags lined with plastic bags of 25kg or 50kg net each.See anhydrous calcium chloride for storage and transportation.
