FAQ

What are the physical and chemical properties of aluminum triphosphate (CAS: 13939-25-8)?

Aluminum triphosphate (CAS: 13939-25-8) is a white, crystalline solid with a molecular weight of approximately 132.14 g/mol. It is insoluble in water but soluble in acids. Chemically, it is highly reactive with hydroxides and acids. Its crystalline structure is monoclinic. It is commonly used in the synthesis of aluminum-based materials and has significant applications in catalysis and adsorbents.

How is aluminum triphosphate (CAS: 13939-25-8) typically synthesized?

Aluminum triphosphate can be synthesized through the reaction of aluminum oxide with phosphoric acid under controlled conditions. Commonly, this involves the stepwise addition of phosphoric acid to aluminum oxide in a stirred reactor, followed by drying and calcination to form the triphosphate. This process requires careful control of temperature and pH to achieve high selectivity and yield.

What industries use aluminum triphosphate (CAS: 13939-25-8)?

Aluminum triphosphate (CAS: 13939-25-8) is widely used in various industries. It is a key component in catalysis, where it serves as an effective support for metal catalysts. In pharmaceuticals, it is used as a thickening agent and in oral medications. Additionally, it finds applications in polymers as a flame retardant and in sensors as a selective adsorbent.

What precautions should be taken when handling aluminum triphosphate (CAS: 13939-25-8)?

Handling aluminum triphosphate requires appropriate safety measures. Wear protective gloves, goggles, and a lab coat. Work in a well-ventilated area or a fume hood to minimize inhalation of dust. Spills should be cleaned up using a suitable absorbent material, and the area should be rinsed with water. Always refer to the Safety Data Sheet (SDS) for specific handling instructions and emergency procedures.
