Triammonium Phosphate Trihydrate(CAS: 25447-33-0)

Triammonium Phosphate Trihydrate is a white crystalline solid with a molecular weight of approximately 229.14 g/mol. It has a high solubility in water, with a solubility of about 25 g/100 mL at 25°C. Chemically, it is stable under normal conditions but may react with acids to release ammonia and phosphoric acid. It forms a stable hydrate structure and has a melting point of 145°C.

Triammonium Phosphate Trihydrate is typically synthesized by the reaction of ammonia with phosphoric acid in the presence of appropriate catalysts, such as zinc oxide. The reaction is carried out under controlled conditions to achieve high yield and selectivity. The product is then dried to form the trihydrate form.

Triammonium Phosphate Trihydrate is used in various industries. It is a key component in the formulation of fertilizers, food additives, and pharmaceuticals. In the polymer industry, it serves as a flame retardant and stabilizer. It is also used in the production of adhesives, sealants, and as a surfactant in cleaning products.

When handling Triammonium Phosphate Trihydrate, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from direct sunlight. In case of a spill, it should be cleaned up using appropriate spill control measures. Always refer to the Safety Data Sheet (SDS) for detailed handling and storage instructions.
