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.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts
the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from
exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has
stopped and CPR if heart action has stopped. Transfer
promptly to a medical facility. When this chemical has
been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit
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.
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.
