FAQ

What are the physical and chemical properties of Calcium Nitrate Tetrahydrate (CAS: 13477-34-4)?

Calcium nitrate tetrahydrate is a white crystalline salt with the formula Ca(NO3)2·4H2O. It has a high solubility in water, with a molecular weight of approximately 236.11 g/mol. Chemically, it is highly reactive with acids and can release nitrogen oxides upon heating. It is stable under normal conditions but decomposes above 100°C to form calcium nitrate and water.

How is Calcium Nitrate Tetrahydrate (CAS: 13477-34-4) typically synthesized?

Calcium nitrate tetrahydrate is typically synthesized by dissolving calcium nitrate in water and then adding anhydrous calcium nitrate to a solution of nitric acid. This process results in the formation of the tetrahydrate. Commonly, the reaction is carried out in a closed system to maintain the water content and ensure the formation of the hydrate. The yield is typically around 85-90%, with a high degree of purity.

What industries use Calcium Nitrate Tetrahydrate (CAS: 13477-34-4)?

Calcium nitrate tetrahydrate is used in various industries, including fertilizers, water treatment, and pharmaceuticals. It is a key component in controlled-release fertilizers and is also used in the production of calcium nitrate solutions for water treatment. Additionally, it has applications in the production of calcium nitrate-based fertilizers and as a reagent in analytical chemistry.

What precautions should be taken when handling Calcium Nitrate Tetrahydrate (CAS: 13477-34-4)?

When handling calcium nitrate tetrahydrate, it is important to wear protective equipment such as gloves and safety goggles. It is flammable in dust form and can react with strong acids, producing nitrogen oxides. It should be stored in a cool, dry place away from heat and open flames. In case of spillage, it should be handled with care and cleaned up using appropriate methods, and the area should be well-ventilated. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
