Preparation or source
From hydrated calcium chloride is heated to 260 ℃ drying dehydration obtained. Can be used to remove arsenic and heavy metals have been refined neutral calcium chloride solution into a mist spray through the nozzle, and 300 ℃ for countercurrent contact with hot air to dry and dehydrated obtained. Used as desiccant of gas, producing alcohols, esters, ethers and acrylic resin when the dehydrating agent. In the food industry as a calcium enhancer, curing agents, chelating agents, desiccant.
Uses
Anhydrous calcium chloride is a commonly used industrial and laboratory desiccant, such as for nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases, dry, but can not be used to dry ethanol, and ammonia. Production of alcohols, esters, ethers and acrylic resin used as a dehydrating agent.
Inorganic industry for manufacturing of metal calcium, barium chloride, various calcium salts (such as calcium phosphate, etc.) raw materials.
The construction industry as antifreeze, to speed up the concrete to harden and increase the capacity of the construction mortar cold.
Haploid breeding of industrial microorganisms used as the medium.
Analytical Chemistry for the determination of iron and steel carbon content, whole blood glucose dissolved, serum inorganic phosphorus and serum alkaline phosphatase activity and so on.
Used as a protective agent aluminum metallurgy, refining agent.
In addition, the fabric used as a fire retardant, harbor anti-fogging agent, road dust agents and food preservatives.
