Calcium dinitrate

Calcium dinitrate is an inorganic chemical compound with the molecular formula CaN2O6 and CAS number 10124-37-5. It has a molecular weight of 164.09 g/mol and appears as white crystalline solid. This calcium salt of nitric acid is highly soluble in water and hygroscopic in nature. It's classified as an oxidizing agent under ADR regulations (Class 5.1, Group III) due to its ability to release oxygen and support combustion when heated.

Calcium dinitrate is a white crystalline solid that is highly soluble in water and hygroscopic, meaning it readily absorbs moisture from air. It has a molecular weight of 164.09 g/mol and decomposes when heated, releasing oxygen. The compound is odorless and has good thermal stability under normal conditions. Its high water solubility makes it readily available for biological processes, while its oxidizing properties require careful handling and storage away from combustible materials.

Calcium dinitrate is primarily used as a nitrogen and calcium fertilizer in agriculture, providing essential nutrients for plant growth. It serves as a concrete additive to accelerate setting and prevent freezing in cold weather construction. The compound is also utilized in wastewater treatment processes for nutrient removal and in the production of other calcium compounds. Additionally, it finds applications in the manufacturing of explosives and pyrotechnics due to its oxidizing properties.

Calcium dinitrate should be handled with appropriate personal protective equipment including safety goggles, gloves, and dust masks to prevent inhalation and skin contact. Work in well-ventilated areas to avoid dust accumulation and ensure good hygiene practices. Keep the material away from heat sources, combustible materials, and reducing agents due to its oxidizing nature. Avoid creating dust clouds and use proper material handling equipment. Always wash hands thoroughly after handling and follow workplace safety protocols.

Calcium dinitrate 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 due to its hygroscopic nature. Store separately from combustible materials, reducing agents, and incompatible chemicals due to its oxidizing properties. Use appropriate storage containers resistant to corrosion and ensure proper labeling. Maintain storage areas clean and implement proper inventory rotation to prevent degradation over time.

Calcium dinitrate contact requires immediate action: for skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15 minutes and seek medical attention. If inhaled, move to fresh air and seek medical help if breathing difficulties occur. For ingestion, do not induce vomiting, rinse mouth with water, and seek immediate medical attention. Always consult safety data sheets for specific first aid measures.

Calcium dinitrate disposal must comply with local environmental regulations and waste management guidelines. Small quantities can often be neutralized and disposed of through industrial waste channels, while larger amounts require specialized hazardous waste disposal services. Never dispose of in regular trash, sewers, or waterways. Contact licensed waste disposal companies familiar with oxidizing agents. Consider recycling or recovery options where available, and always consult local authorities for specific disposal requirements in your region.

Calcium dinitrate is classified under ADR as Class 5.1 (oxidizing substances), Group III for transportation purposes. It requires appropriate packaging according to transport regulations, typically in UN-approved containers with proper labeling and documentation. Transport vehicles must comply with ADR requirements for oxidizing substances, including proper ventilation and separation from incompatible materials. Drivers need ADR certification, and transport documents must include all necessary safety information and emergency response procedures.

Calcium dinitrate is regulated under various European chemical legislation including REACH and CLP regulations. It requires proper classification, labeling, and safety data sheet provision according to CLP standards. The substance is not currently identified as a Substance of Very High Concern (SVHC) under REACH. Transport regulations under ADR apply due to its oxidizing properties. Users must comply with workplace safety regulations, environmental discharge limits, and proper waste disposal requirements according to local and European legislation.
