calcium chloride

Feathers:
colorless cubic crystal. white or white porous or grain, honeycomb. oderless, slightly bitter taste. Relative density of 2.15(25centigrade thermometer). melting point of 782centigrade thermometer;, boiling point of 1600centigrade thermometer;. strong moisture absorption. It is easy to deliquescent in the air. Easy to soluble in water and at the same time release lots of heat. It's water solution is slight acidity. soluble with alcohol, acetone and vinegar. React with ammonia and alcohol to produce CaCl2?NH3 & CaCl2?C2H5OH. Under the common temperature, crystal to produce Hexahydrate. add heat to 30centigrade thermometer; and it is soluble with self crystal water. Continously add heat, lose water, to 200centigrade thermometer; become dihydrate. Add heat to
260centigrade thermometer; it becomes water porous calcium chlorde,anhydrous.
Specification: ( industrial salt)
