Structure

Applications – Phosphorus pentoxide is a versatile compound and used in wide range of applications:

Organic synthesisIt can be used as a reagent for condensations in organic synthesis and polymerisation reactions. Typical uses include cyclisation / ring closures in such reactions as acetylation, alkylation, production of amines, acid amides, cyclic ketones, cyclic olefins or oxygen and sulphur heterocyclic compounds.
Catalyst productionIt can be used in the manufacture of special phosphoric acid supported catalysts.
Specialty inorganic phosphatesPhosphorus pentoxide can be used in the manufacture of specialty sodium and ammonium phosphates.
Polyphosphoric acidsVarious grades of superphosphoric and polyphosphoric acids can be manufactured by blending phosphorus pentoxide with phosphoric acid.
GlassBeside silicon dioxide and boron trioxide also phosphorus pentoxide is used for glass making.
Phosphate estersIt can be used to produce phosphate esters with a mono/di ester content. The acid is reacted directly with the appropriate alcohol or phenol to produce the acidic phosphate ester.
Drying agentBecause of its strong hygroscopic properties phosphorus pentoxide can be used as a drying agent.
FertilizersIn production of ammonium polyphosphate.
SurfactantsIn manufacture of cetyloleyl ether phosphoric acid, cetylstearyl ether phosphoric acid, nonylphenol ether phosphoric acid.
