Calcium dichlorite

Calcium dichlorite is an inorganic chemical compound with the formula CaCl2O4 and CAS number 14674-72-7. This substance has a molecular weight of 174.98 g/mol and belongs to the chlorite family of compounds. It is primarily used as an oxidizing agent in various industrial applications due to its chemical properties and reactivity with organic materials.

Calcium dichlorite is a crystalline solid that typically appears as white to pale yellow powder or granules. It is highly soluble in water, forming clear solutions that may have a slight chlorine-like odor. The compound is hygroscopic, meaning it readily absorbs moisture from the air, and decomposes when heated, releasing oxygen and chlorine compounds.

Calcium dichlorite is primarily used as a bleaching agent in the textile and paper industries due to its strong oxidizing properties. It also serves as a disinfectant and sanitizer in water treatment applications. Additionally, it finds use in certain chemical synthesis processes as an oxidizing reagent and in specialized cleaning formulations for industrial applications.

Calcium dichlorite requires careful handling with appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas to avoid inhalation of dust or vapors. Avoid contact with combustible materials, acids, and reducing agents as these can cause dangerous reactions. Always use non-sparking tools and equipment when handling this oxidizing substance.

Calcium dichlorite should be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from combustible materials, acids, ammonia, and organic compounds to prevent dangerous reactions. Use appropriate secondary containment and ensure storage areas comply with local fire safety regulations.

In case of skin contact with calcium dichlorite, immediately flush the affected area with plenty of water for at least 15 minutes and remove contaminated clothing. For eye contact, rinse thoroughly with water for at least 15 minutes. If inhaled, move to fresh air immediately. If ingested, do not induce vomiting and seek immediate medical attention. Always consult emergency services for serious exposures.

Calcium dichlorite waste must be disposed of according to local, national, and international waste regulations. Contact licensed waste management companies for proper disposal as it cannot be disposed of with regular waste. Small quantities may be neutralized carefully under controlled conditions before disposal, but this should only be done by trained professionals following established safety protocols.

Calcium dichlorite is classified under ADR transport regulations as Class 5.1 (Oxidizing substances), Packing Group II. This classification requires specific packaging, labeling, and documentation for transport. Use UN-approved packaging and ensure proper hazard labels are displayed. Transportation must comply with international dangerous goods regulations and be handled by certified carriers experienced with oxidizing materials.

Calcium dichlorite is subject to standard chemical regulations including REACH registration requirements in Europe and CLP classification for hazard communication. While not classified as an SVHC (Substance of Very High Concern), it must comply with workplace safety regulations, transportation laws for dangerous goods, and environmental protection standards. Users must maintain safety data sheets and follow occupational exposure limits.
