| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | calcium chloride hexahydrate is a colorless three-party crystal-like substance, with white or off-white crystals for general commodities. Solubility is soluble in water, soluble in alcohol. The calcium chloride hexahydrate loses four crystal water when heated to 30 ° C., and the heating is continued to 200 ° C. To lose all crystal water to become anhydrous calcium chloride. Strong humidity. It can be used as a refrigeration carrier, anti-freezing agent and flame retardant for cotton fabrics; It is also used as an additive for concrete and building mortar, which can accelerate the hardening of concrete and increase the cold resistance of building mortar. |
| Application | calcium chloride hexahydrate is mainly used as desiccant, dehydrating agent, refrigerant, anti-freeze agent of aviation and automobile internal combustion engine, fabric fire retardant, food preservatives, etc.; Can also be used as a refrigeration carrier and as anti-freezing agent, can accelerate the hardening of concrete and increase the cold resistance of building mortar. Used as a preservative. Flame retardants for finishing and finishing of cotton fabrics. |
| solubility in water (g/100ml) | grams dissolved per 100ml of water at different temperatures (℃): 59.5g/0 ℃;64.7g/10 ℃;74.5g/20 ℃;100g/30 ℃;128g/40 ℃ 137g/60 ℃;147g/80 ℃;154g/90 ℃;159g/100 ℃ |
| toxicity | see calcium chloride anhydrous. |
| Use | used as a refrigeration carrier and antifreeze used as a refrigeration carrier and as an antifreeze, it can accelerate the hardening of concrete and increase the cold resistance of building mortar. Used as a preservative. Flame retardants for finishing and finishing of cotton fabrics. used for anti-freezing, anti-corrosion, cement, fabric fire prevention, etc. calcium chloride is mainly used as desiccant, dehydrating agent, refrigerant, aviation and automobile internal combustion engine anti-freezing agent, coagulation anti-freezing agent, fabric fire retardant, food preservatives, etc. |
| production method | waste liquor recovery method of soda ash distillation waste liquid (containing calcium chloride 100g/L, sodium chloride 43~50g/L, etc.), after purification, clarification, by multiple effect evaporator evaporation, when the calcium chloride content of about 40%, the solution of sodium chloride almost all precipitation, sodium chloride is separated by centrifugation, and the filtrate is clarified and sent to the evaporator to continue evaporation and concentration. When the solution is evaporated to a relative density of 1.37, the solution is cooled to room temperature to precipitate crystals, which are separated by centrifugation, finished calcium chloride hexahydrate was prepared. Hydrochloric acid limestone powder method add 31% hydrochloric acid and limestone powder in a reactor with a ratio of 2.2: 1, react with stirring to generate calcium chloride solution, send it into a clear tank with stirring, and then add milk of lime, the pH value of the solution is 8.5~9, then the precipitation of iron hydroxide and magnesium hydroxide is clarified, the impurities are removed by filtration, and the purified calcium chloride solution is concentrated to a relative density of 1.37 by evaporation, after cooling to room temperature, the crystals were precipitated and centrifuged to obtain a calcium chloride hexahydrate product. CaCO3 + 2HCl → CaCl2 + H2O + CO2 |
