Phosphorous Pentoxide（P2O5）
P2O5 is a kind of light white minicrystal powder which is made by burning phosphorus with excess oxygen.
P2O5 is a basic material and reagent often used in chemical industry.
Phosphorous acid is the acid anhydride of orthophosphoric acid (H3PO4). It can easily absorb moisture and then be transformed into H3PO4 by water. When reacting with water, it can produce lots of heat.

P2O5 can be used to make special catalyst based on phosphoric acid.
P2O5 can be used to make special sodium phosphate and ammonia phosphate.
Super phosphoric acid and poly phosphoric acid can be made by mixing P2O5 and phosphoric acid.
P2O5 can be used as colorless condensating agent or firming agent in making transparent resin.
P2O5 can be used to manufacture phosphate mono ester and phosphodiester. Phosphoric acid will produce acid ester if directly reacting with appropriate alcohol or phenol. P2O5 can give off phosphorous alkylamine if reacted with alkylamine. Due to its hygroscopicity, P2O5 can be used as drying agent.
P2O5 can be used as the catalyst for making blown bitumen as well as for bitumen. It can improve the viscosity of bitumen.
