FAQ

What are the physical and chemical properties of Hexasodium tetraphosphate (CAS: 7727-67-5)?

Hexasodium tetraphosphate is a crystalline compound with a molecular weight of approximately 510.94 g/mol. It is slightly soluble in water, with a solubility of about 2.5 g/L at 25°C. Chemically, it is highly reactive in acidic solutions, forming orthophosphate and releasing sodium ions. It has a melting point of around 220°C and a boiling point of 1364°C under vacuum.

How is hexasodium tetraphosphate (CAS: 7727-67-5) typically synthesized?

Hexasodium tetraphosphate is synthesized through the reaction of sodium hypophosphite with phosphoric acid in the presence of a catalyst like sodium hydroxide. The process involves the formation of sodium tetraphosphate, which is then neutralized with excess sodium hydroxide to produce the final product. The yield is typically around 90%, and the selectivity is excellent, with minimal by-products.

What industries use hexasodium tetraphosphate (CAS: 7727-67-5)?

Hexasodium tetraphosphate is widely used in the food industry as a water softener and emulsifier. It is also used in detergents for fabric softening and in the paper industry as a deflocculant. Additionally, it is utilized in the pharmaceutical industry as a tablet disintegrant and in the construction industry as a water treatment agent.

What precautions should be taken when handling hexasodium tetraphosphate (CAS: 7727-67-5)?

When handling hexasodium tetraphosphate, it is important to wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. Handling should be done in a well-ventilated area or fume hood to avoid inhalation. Spills should be cleaned up immediately using appropriate absorbents, and the area should be thoroughly rinsed with water. Always refer to the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
