| | Calcium chloride hexahydrate Usage And Synthesis |
| Chemical Properties | Calcium chloride is a colorless to off-white
crystalline solid which is deliquescent (absorb water).
When heated, crystals lose water @ 100C. | | Uses | Calcium chloride hexahydrate has been used as a test compound for measuring the overall activity of low-molecular-weight antioxidants in biological samples by using ′total antioxidative capacity′ inhibition assay. | | Uses | Calcium chloride hexahydrate is a phase changing material (PCM) that is widely used in solar energy storage and building applications. | | Definition | ChEBI: A hydrate that is the hexahydrate form of calcium chloride. | | General Description | Calcium chloride hexahydrate is a non-toxic salt hydrate that can be used in phase change heat storage of low temperature heat. It has a latent heat of fusion as high as 170-190 kJ/Kg and a melting temperature of 29-30°C. | | Biochem/physiol Actions | Calcium chloride act as precipitants during protein crystallization process. It also enhances the competence of Escherichia coli cells in transformation experiments. It strengthen β-lactoglobulin gels by forming crossbridges. | | Potential Exposure | Calcium 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. | | Shipping | There are no label or maximum shipping quantity requirements set by DOT. | | Incompatibilities | The 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. |
