Calcium Chloride Versatile Desiccant for Drying Gases and Production of Alcohols Esters and Acrylic Resins

Calcium chloride (chemical formula: CaCl2) is a white or slightly yellow solid inorganic compound, belonging to the category of salts. It is a typical ionic halide and widely used in various fields due to its high solubility, hygroscopicity, and dehydration. According to its hydration form, it exists in different physical forms, with the most common being dihydrate (CaCl2 · 2H2O). Its high solubility allows it to quickly dissolve in water, releasing a large amount of heat, making it very useful in applications that require rapid heating or drying. In addition, calcium chloride is often used in salt water, road deicing agents, and desiccants used in refrigeration equipment.

1. Used as a versatile desiccant for drying gases such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide, etc. Used as a dehydrating agent in the production of alcohols, esters, ethers, and acrylic resins. Calcium chloride aqueous solution is an important refrigerant for freezers and ice making, which can accelerate the hardening of concrete and increase the cold resistance of building mortar. It is an excellent building antifreeze. Used as a defogging agent and road dust collector for ports, as well as a fabric fire retardant. Used as a protective and refining agent for aluminum magnesium metallurgy. It is a precipitant used in the production of lake pigments [26]. Used for de ink processing of waste paper. It is the raw material for producing calcium salts.

3. Used as a desiccant, road dust collector, defogger, fabric fire retardant, food preservative, and in the manufacture of calcium salts.
4. Used as a lubricant additive.
5. Used as an analytical reagent.
6. Mainly used to treat hand foot twitching, urticaria, exudative edema, intestinal and ureteral colic, magnesium poisoning, etc. caused by decreased blood calcium.
7. Used as a calcium fortifier, hardener, chelating agent, and desiccant in the food industry.
8. Can increase the permeability of bacterial cell walls.
