Description
The solid reacts with water violently to produce phosphoric acid. It is prepared by phosphorus reaction with excess oxygen. The crude is then purified by sublimation. melting point 580°C (under pressure); sublimes at 300°C. Phosphorus pentoxide structure consists of each P atoms linked to three others by oxygen bridges with a terminal oxygen atom.specific gravity 2.39; Phosphorus Pentoxide is a white, flammable, dangerous, and extremely deliquescent solid;
Applications
Phosphorus pentoxide is usual material and reagent in chemical industry, this product is widely used inthe industries of medicine, coating auxiliaries, printing and dyeing auxiliaries, anti static additive, titanate coupling agent, phosphorus oxychloride, and chemical.
The purifying agent used as a desiccant, dehydration agent, sugar, and used to produce phosphoric acid, phosphorus compound and aerosol, etc. used as semiconductor silicon doped source, dehydration desiccant, organic synthesis.
Dangerous property
Non-combustible, but the water and organic matter such as wood, cotton or grass dramatic reaction to release heat, which can cause burning. Corrosive to the skin, mucous membranes, even 1mg/m3 the concentration of dust, but also unbearable.
