With different crystallized water contents ,it can be

dihydrate or anhydrous .Liquid calcium chloride is a 

colorless,clear solution,As calcium chloride has such

attracting mositure from the air and surroundings

dissoliving at very low temperature.

1.Used in highway, expressway, parking lot and port and as a dryer to dry

  nitrogen, oxygen, hydrogen, hydrogenchloride and sulfur dioxide etc.

2.Act as dehydration agent when producing alcohol, ester, ether and

 acrylic acid.

3.Calcium chloride is a kind of important cryogen used by freezing machine 

 and when making ice.

4. It can increase hardness of concrete and increase cold resistance ability

  of the construction.

5. In port, acts as fog removing agent and dust collecting agent on road and

   fireproof agent of textile and acts as

  a protective agent and refining agent used in aluminum magnesium metallurgy.

6.Act as precipitator in producing lake paint. It is a kind of raw material of 

  producing calcium salt. In algae sodiumand bean industry it acts as flocculation.
