Calcium chloride can be produced directly from limestone and hydrochloric acid, paticularly for applications in medicine and requesting for high-purity, but large scale production is found as a by-product of the Solvay process.
(1)Calcium chloride is used to make desiccant in various industries (2) Refined calcium chloride can be used in food, electronic, and leather industry; used in the organic chemical production processing, petroleum distilling, and also used as a mixer in ether alcohol. (3) Used as a snow-thawing agent for highways, parking lots, airports and docks etc. (4) Used to prevent dust, grime and mine dust. (5) calcium chloride is used in oil well drilling, used as well drilling fluid, completion fluid, well cementation fluid, and workover fluid, and it is also used as dehydrant in petroleum chemical industry. (6) Used to make emulsion coagulant in rubber industry. (7) Used to make chlorating agent and additives in ferrous metallurgy industry. (8) Used to make additives in paper making industry. (9) Used to make early strengthen agent (concrete strengthening agent and coating material coagulating agent etc) in construction industry. (10)Used as a raw chemical material, sulfate radical removal agent, and sodium alginate coagulating agent in chemical industry. (11)Calcium chloride is used as a cooling agent in refrigerating industry, used as a media between air and fluid in refrigerating technique for air conditioning system. (12)Used to prevent putrefaction for wheat, apple, and cabbage etc; used as a foodstuff antiseptic.
