Phosphorus Pentoxide
Synonyms: Phosphoric Anhydride; Phosphorus Oxide; Sicapent; Eaton’s Reagent; Phosphoric Oxide; Phosphor Pentoxide
Executive Standard: GB/T 2305-2000
Chemical formula: P2O5
Molecular weight: 141.94
RIDADR: UN 1807 8/PG 2
Characteristics: Easily deliquescent white crystalline powder, relevant density is 0.9g/cm3, sublimate at 300℃, melting point is 580-585℃, vapor pressure is 133.3 Pa (384℃). When heating to higher temperature, the crystalline changes to amorphous vitreum, absorbing moisture when expose to the air. omitting heat and white smoke when soluble in water.

Use: P2O5 is mainly used as industry raw materials and reagent. Widely used in pharmaceuticals, coating additive, dyeing auxiliary, antistat, coupling agent of organic titanate, phosphorus oxychloride, etc. Also used for producing high purity phosphoric acid, drying agent for gas and liquid, dehydrant for organic synthesis, and for the manufacturing of organophosphorus ester.
Health Hazard: Non-ignitable, reacting vigorously and omitting heating or burning while meeting water and organic matters such as wood, cotton or grass. And omitting heat and smoke when soluble in water. Slightly corrosive to metals when affected with damp. Powder and fumes in the air are irritating to eyes and the respiratory tract. Particles in contact with eye react vigorously and even a small amount may cause permanent burns. Contact with the skin will cause severe burns. Ingestion will damage the gastrointestinal tract. Corrosive to skin, mucous membranes and eyes.
