Chemische Eigenschaften
Calcium chloride is a colorless to off-white crystalline solid which is deliquescent (absorb water). When heated, crystals lose water @ 100C.
Verwenden
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.
Verwenden
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.
Allgemeine Beschreibung
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.
mögliche Exposition
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.
Versand/Shipping
There are no label or maximum shipping quantity requirements set by DOT.
Inkompatibilitäten
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.
