Calcium Hypochlorite 65%  Chemical appearance:

Calcium Hypochlorite 65% appears as a white or light grey powder, tablets, granules or a mixed powder. It reacts in both water and alcohol with some level of solubility. It does not have any strong odors. In addition, it melts around 100 degrees Celsius into an aqueous form.

• • Calcium hypochlorite is a widely used chemical for disinfecting drinking water. Manufacturers commonly supply the product at approximately 65% purity, and users typically apply it in small quantities to achieve effective disinfection.

    Water-treatment facilities also use calcium hypochlorite to sanitize public swimming pools. Operators may combine it with other treatment chemicals when appropriate. However, they must not mix calcium hypochlorite directly with chlorine-containing chemicals because incompatible combinations can produce hazardous reactions. Calcium hypochlorite provides an alternative to sodium hypochlorite, which is also widely used for water and surface disinfection.

    Chemical manufacturers can also use calcium hypochlorite as a source of hypochlorite in haloform reactions, including processes used to produce chloroform. Chloroform has applications as an industrial solvent and chemical intermediate, although modern uses are more limited than in the past. The haloform reaction involves the reaction of a methyl ketone or a related compound with a hypohalite under suitable conditions.

    Calcium hypochlorite also serves as a disinfectant during certain hazardous-material incidents, including situations involving radioactive contamination or spills of toxic chemicals. Specialized response teams may use it to oxidize and neutralize certain hazardous substances, depending on the material involved and the applicable safety procedures.

    One of the other major applications of calcium hypochlorite involves bleaching. Manufacturers use it to bleach materials such as fibers, cloth, wood pulp, and silk. Its strong oxidizing properties help remove color-producing compounds and other organic impurities from these materials.
