It is a powerful desiccant. This white crystalline solid is the anhydride of phosphoric acid. This is a white, flammable, dangerous, and extremely deliquescent solid. Contact with eyes will result in severe eye damage, even blindness. You’re mixing things up. Between the commercially important P4O6 and P4O10, phosphorus oxides are known with intermediate structures. DESICCANT CAPACITY OF CARRIER-BASED PHOSPHORUS PENTOXIDE An absorption tube (25 x 350 mm) charged with 8-12 mesh granules, contained 28-2 g of desic- cant. Phosphorus pentoxide is a chemical compound with molecular formula P4O10 (with its common name derived from its empirical formula, P2O5). 99% Phosphorus Pentoxide for Desiccant, Find Details about Diphosphorus Pentoxide, P2o5 from 99% Phosphorus Pentoxide for Desiccant - Jiangsu Bohan Industry Trade Co., Ltd. Fiction. Where substances are stable in air and melt above 100°C, drying in an air oven may be adequate. Phosphorus pentoxide is a powerful desiccant suitable for drying neutral and acid gases, saturated alipathic and aromatic hydrocarbons, nitriles, alkyl and acryl halogenides, and carbon disulfide.
