United States’ CaCl2 production

United States Production of Calcium Chloride (1000 st of equivalent 77-78% CaCl2)... 

H3[PWi204o] is a white crystalline solid that, as isolated, possesses about 20-29 water molecules per Keggin unit. In order to reach the hexahydrate state, the final product is dried over CaCl2 in a desiccator for several days. It is highly soluble in water, ethanol, ether, acetonitrile, and acetone, but is insoluble in chloroform and hydrocarbons, and decomposes in basic aqueous solution (e.g., 0.5 M NaOH). IR (cm ) 1080 pJP-O), 990 p(W=0), 890 uJW-O-W), 804 uJW-O-W). Powder XRD (20 in degrees, Cu Ka radiation, 2 = 1.5418 A) 10.2, 14.5, 17.8,...
