Calcium dipermanganate

Calcium dipermanganate is an inorganic chemical compound with the molecular formula CaMn2O8 and CAS number 10118-76-0. This compound has a molecular weight of 277.95 g/mol and belongs to the permanganate family of chemicals. It contains calcium and manganese in their oxidized states, making it a powerful oxidizing agent with distinctive chemical properties used in various industrial applications.

Calcium dipermanganate is typically a crystalline solid with a characteristic dark purple or violet color, similar to other permanganate compounds. It is highly soluble in water, forming intensely colored purple solutions. The compound is hygroscopic and tends to absorb moisture from air. It demonstrates strong oxidizing properties due to the presence of permanganate ions and decomposes when heated, releasing oxygen gas.

Calcium dipermanganate serves as a powerful oxidizing agent in various industrial processes including water treatment, chemical synthesis, and analytical chemistry. It is used for disinfection and sterilization purposes due to its strong oxidizing properties. The compound also finds applications in laboratory settings as a reagent for organic synthesis and in specialized chemical manufacturing processes where controlled oxidation reactions are required.

Calcium dipermanganate requires careful handling using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas to avoid inhalation of dust particles. Avoid contact with combustible materials, organic substances, and reducing agents as the compound can cause vigorous reactions. Use non-metallic tools and containers when handling to prevent unwanted catalytic reactions.

Calcium dipermanganate must be stored in a cool, dry place away from heat sources, direct sunlight, and moisture. Keep the compound in tightly sealed, non-metallic containers to prevent contamination and decomposition. Store separately from combustible materials, organic compounds, acids, and reducing agents to avoid dangerous reactions. Ensure proper ventilation in storage areas and maintain temperatures below 25°C for optimal stability.

Calcium dipermanganate contact requires immediate action depending on exposure type. For skin contact, remove contaminated clothing and flush affected area with plenty of water for at least 15 minutes. In case of eye contact, rinse thoroughly with clean water and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention while providing the safety data sheet to medical personnel.

Calcium dipermanganate disposal must comply with local and national hazardous waste regulations. The compound should be treated as hazardous chemical waste and disposed of through licensed waste management companies. Small quantities can be neutralized by careful reduction with appropriate reducing agents under controlled conditions before disposal. Never discharge directly into sewers, waterways, or regular waste streams due to its oxidizing nature and environmental impact.

Calcium dipermanganate is classified under ADR Class 5.1 (Oxidizing substances) with Packing Group II, indicating moderate danger level during transport. It must be packaged in appropriate UN-specification containers and labeled with proper hazard markings. Transport vehicles require placarding and documentation including transport documents and emergency response information. Drivers must hold ADR certification for Class 5.1 materials and follow specific routing restrictions.

Calcium dipermanganate is subject to various chemical regulations including REACH registration requirements in Europe and CLP classification rules. The compound is not currently identified as a Substance of Very High Concern (SVHC) under REACH regulation. However, it must comply with occupational safety standards, transport regulations (ADR), and local environmental protection laws. Users must maintain safety data sheets and implement appropriate risk management measures.

Calcium dipermanganate is available through specialized chemical distributors across Europe, including OYSI, which supplies high-quality chemical products to industrial and professional customers. When purchasing, ensure the supplier provides proper documentation including certificates of analysis, safety data sheets, and regulatory compliance information. Contact qualified distributors for specific grades, quantities, and technical specifications required for your applications while ensuring proper handling and storage capabilities.
