Product Description


Phosphorus Pentoxide HP is a white crystalline solid, extremely hygroscopic. It is formed by burning elemental phosphorus in the abundant presence of oxygen. Most practical applications and uses of Phosphorus Pentoxide HP are based around its extreme affinity to water, which makes it an excellent dehydrating agent. The dissolution in water is exothermic and demands due care. Phosphorus Pentoxide HP is used in the production of organic phosphate and polyphosphoric acid. Another
application areas are pharmaceuticals and vitamins, catalysts and drying agents.
