Properties:

1.Phosphorus Pentoxide is a white, flammable, dangerous,



2.deliquescent solid;



3.specific gravity 2.39;



4.melting point 580 C (under pressure);



5. sublimes at 300 C.



6.The solid reacts with water violently to produce phosphoric acid.



7.Phosphorus pentoxide structure consists of each P atoms linked to three others by oxygen bridges with a terminal oxygen atom.



8.It is used as a strong dehydrating agent, capable even of dehydrating concentrated sulphuric acid into sulphur trioxide.



9. It dehydrates amides to nitriles. End applications include manufacture of phosphorus compounds, purifying sugar, optical glass, heat-insulating glass, medicine, pesticide and surfactant manufacturings.







Usage: Used to make high purity phosphoric acid and phosphoric salt,make poly-phosphoric acid, used for the pharmaceutical industry, dye additives, Combustion.
