About Calcium Chloride Anhydrous

Calcium chloride anhydrous is one of a few anhydrous inorganic salts that easily form a hydrate. The ability to form a hydrate is important because it permits anhydrous calcium chloride to be used to remove little bits of water from any organic solution. Cautionary Note: The formed hydrates are not very stable, which means they must be removed before a dried solution created from them is heated.
Calcium chloride anhydrous used to be the basis for the production of calcium. This was achieved by electrolysis. Now, at least commercially, most calcium is produced by the reduction of lime via aluminum.
