Calcium chloride dihydrate Usage And Synthesis
DescriptionCalcium chloride dihydrate (CaCl2﹒2H2O) is the hydrate form of calcium chloride. Calcium chloride is an inorganic compound consisting of calcium and chloride. It has various kinds of applications. For example, it can be used as a desiccant due to its high hygroscopicity; used for the deicing and dust control; for road surfacing; as brine for refrigeration plants, ice and cement; increasing the water hardness in the swimming pools; as a food additives; increasing the cell membrane permeability to facilitate the genetic transformation of cells; for the treatment of hypocalcemia in which the body requires a prompt increase in blood plasma calcium levels, For its production, it can be either produced directly from limestone or produced by the Solvary process as the by-product. In addition, it can also be obtained by purification from brine.
Chemical Propertiescolourless crystals or white crystalline powder
Chemical PropertiesCalcium chloride is a colorless to off-white crystalline solid which is deliquescent (absorb water). When heated, crystals lose water @ 100C.
Usescosmetic ingredient
UsesPreparation of calcium standard solutions; electrolyte.
DefinitionChEBI: A hydrate that is the dihydrate form of calcium chloride.
Brand nameCal Plus (Mallinckrodt).
Potential ExposureCalcium chloride is used as road salt for melting snow, a drying agent in desiccators, for dehydrating organic liquids and gases, in refrigeration brines and antifreeze, as a dust-proofing agent, food additives, concrete hardening accelerator, and others. May react with strong oxidizers.
ShippingThere are no label or maximum shipping quantity requirements set by DOT.
Purification MethodsCrystallise it from ethanol. It is hygroscopic. It loses H2O at 200o so it can be dried at high temperatures to dehydrate it. The hexahydrate [7774-34-7] has m 30o and d 1.67.
IncompatibilitiesThe solution in water is a weak base. Reacts with zinc in presence of moisture, forming highlyflammable hydrogen gas. Dissolves violently in water with generation of much heat. Incompatible with water, bromine trifluoride; 2-furan, percarboxylic acid. May attack some building materials and metals in the presence of moisture.
