Strong Dehydrating Capability: Highly hygroscopic and easily deliquescent, making it an extremely effective drying and dehydrating agent.
High Thermal Stability: Exhibits a high melting point (580–585 °C) and stable performance under elevated temperatures, suitable for high-temperature applications.
Phase Versatility: Can transition from crystalline form to amorphous glass upon heating under pressure, offering flexibility in different processing conditions.
Selective Solubility Characteristics: Insoluble in acetone and ammonia but soluble in sulfuric acid, allowing controlled application in specific chemical systems.
Product Description of Phosphorus pentoxide CAS#1314-56-3
Phosphorus pentoxide, or phosphoric anhydride, is a phosphorus oxide made by burning phosphorus in dry air. It is highly deliquescent white powder or colorless monoclinic crystal at room temperature.
It melts at 580–585°C, sublimes at 347°C with relative density 2.39, and turns into glassy form under pressure at 563°C. It dissolves in sulfuric acid, yet insoluble in acetone and ammonia.
Product Application of Phosphorus pentoxide CAS#1314-56-3
Phosphorus pentoxide is widely used as desiccant, dehydrant, organic condensation agent and lab reagent, also for sugar refining and fire suppression.
