Uses

Anhydrous calcium chloride is a commonly used industrial and laboratory desiccant, such as for nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases, dry, but can not be used to dry ethanol, and ammonia. Production of alcohols, esters, ethers and acrylic resin used as a dehydrating agent.

Inorganic industry for manufacturing of metal calcium, barium chloride, various calcium salts (such as calcium phosphate, etc.) raw materials.
