Anhydrous calcium chloride is a white granular or powdered substance, highly soluble in water and releasing a large amount of heat. It has extremely strong hygroscopicity and can rapidly absorb moisture from the air and even deliquesce. It has a high solubility, its aqueous solution is neutral, and it is not prone to freezing at low temperatures. It has stable chemical properties, is not easy to decompose, and can react with ammonia and alcohol substances. It has a wide range of uses and is mainly used as a desiccant. It can dry gases such as nitrogen and oxygen, as well as liquids such as ethers and esters. It is used in industry as an antifreeze agent, de-icing agent and road dust removal agent. It can accelerate the hardening of concrete in construction and be used as a coagulant or preservative in the food industry. In addition, it is also used for dehydration treatment in oil extraction and chemical production, and is an economical and efficient multi-functional chemical.
