Phosphorus Pentoxide Applications
Dehydrating Agent
Phosphorus Pentoxide is used as a strong drying and dehydrating agent. Many reactions that require the removal of a water molecule can utilize P2O5 such as the dehydration of amides to nitriles.
Starting Material
The compound is the starting material for phosphate esters used as surfactants and extraction agents. It can be used in the manufacture of other phosphorus compounds such as high-quality Phosphoric Acid.
Catalyst Production
It can be used in the manufacture of special phosphoric acid supported catalysts.
Glass
It is used to manufacture optical glass and heat-insulating glass.
Organic Synthesis
The compound can be used in the preparation of organic intermediates in the pharmaceutical and color and dyes industries. It is also used as a reagent for condensations in organic synthesis and polymerization reactions.
