Calcium chloride dihydrate powder

Calcium chloride dihydrate is a white or gray chemical, mostly granular presentation, the market is now the largest area of calcium chloride dihydrate is used as a deicing salt.It is easily soluble in water, while releasing a lot of heat, its aqueous solution was slightly alkaline. Soluble alcohol, acetone, acetic acid. With ammonia or ethanol,CaCl28NH3 and CaCl24C2H5OH complexes were generated respectively. Crystallization of the solution at low temperatures and precipitation of hexahydrate, gradually heated to 30 ℃ when it is dissolved in its own crystal water, continue to gradually dehydration heating, to 200 ℃ into dihydrate, and then heated to 260 ℃ becomes White porous anhydrous calcium chloride.
