    Phosphorus Pentoxide

                                                                                  English name: Phosphorus Pentoxide
                                                                                    Cas No. 1314-56-3

    Appearance: white powder
    Usage: Phosphorus pentoxide is a pure white powdery solid. It is yellow powder when the purity is insufficient. It has a special pungent smell. Phosphorus pentoxide is highly corrosive and toxic and may cause severe irritation or chemical burns if improperly used in contact with the eyes or skin. Ingesting or inhaling too much phosphorus can lead to phosphorus poisoning, with symptoms including nausea, vomiting, diarrhea, headache, difficulty breathing and, in severe cases, death. Phosphorus pentoxide is often used as a desiccant and dehydrating agent, and is also the main material for the manufacture of phosphoric acid, pesticides, and phosphates.

      Application  


    1. Phosphorus pentoxide is mainly used as a desiccant of gases and liquids, a dehydrating agent of organic synthesis, an antistatic agent of polyester resin, a drug and a refined preparation of sugar, as well as a parent material for the production of high purity phosphoric acid, phosphate, phosphide and phosphate ester, and can also be used for the manufacture of phosphorus pentoxide sol and H-type aerosol.

    2. It is used in the manufacture of optical glass, ultraviolet glass, heat insulation glass, glass-ceramics and opacite glass, etc., to improve the dispersion coefficient of glass and the ability to pass ultraviolet light.

    Vapor Pressure:

    1 mm Hg ( 384 °C)

    Vapor Density:

    4.9 (vs air)

    Flammability characteristics:

    Non-combustible. But encountering water and organic materials such as wood, cotton or straw, it reacts violently to release heat, may cause a fire.

    Experimental Properties:

    Very deliquescent. Readily absorbs moisture from the air. Exothermic hydrolysis by water to form phosphoric acid. The reaction with alcohol is similar.|Heat of formation: -365.83 kcal/mole. Specific heat: 0.170 cal/g/ °C. Heat of fusion: 8.2 kcal/mole.|Sublimation temperature 360 °C.|Most important chemical property is its avidity for water.
