Compare Products: Select up to 4 products. It reacts with water to form phosphoric acid H3PO4. Phosphorus pentoxide is a chemical compound with molecular formula P 4 O 10 (with its common name derived from its empirical formula, P 2 O 5).This white crystalline solid is the anhydride of phosphoric acid.It is a powerful desiccant and dehydrating agent. Preparation. It is most commonly used to remove humidity that would normally degrade or even destroy products sensitive to moisture. It exists as a dimer. It is used extensively in organic synthesis as a dehydrating agent. PHOSPHORUS PENTOXIDE CAS No. When saturated with water from a continuous flow of air of high humidity, its capacity was found to be 5-15 g of water or 18-3 % of its original … Port Shanghai or Chongqing As an ACS grade quality reagent, its chemical spec It is a powerful desiccant and … PRODUCT FEATURES. 79610-500G Pkg. This white crystalline solid is the anhydride of phosphoric acid. Phosphorus pentoxide, P2O5 /CAS:1314-56-3, Desiccant, dehydrating agent---- packing weight (Net weight) can be customized accordingly. Even though a single molecule of the compound has a molecular formula of P 4 O 10 , it is still called phosphorus pentoxide on account of its … Its molecular formula is P 4 O 10 but it is found as a dimer of P 2 O 5. 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. P 2 O 5 (or P 4 O 10) can be prepared by burning elemental P 4 (tetra-phosphorus) in an environment containing a sufficient amount of oxygen. It has several other names such as phosphoric anhydride, phosphorous (V) oxide, diphosphorus pentoxide etc. we always expose new phosphorous pentoxide). Size 500 g Description Phosphorus pentoxide, desiccant, with moisture … It is highly hygroscopic and is, therefore, used as a dehydrating agent and as a desiccant. Phosphorus pentoxide is an acid anhydride that is obtained from phosphoric acid. *Please select more than one item to compare No. ( Two identical molecules linked together) P4O10 -Molecular formula. Phosphorus pentoxide is normally used as an industrial desiccant and plays a role as an intermediate reactant to turn acid into their anhydride counterparts. 1314-56-3 . Mfr. Phosphorus Pentoxide is a chemical compound with molecular formula P 4 O 10 (with its common name derived from its empirical formula P 2 O 5). It is a white crystalline solid which is used as a powerful dehydrating agent. phosphorus pentoxide. List of desiccants: Search results for phosphorus pentoxide at Sigma-Aldrich. P2O5 - Diphosphorous Pentoxide. Phosphorus pentoxide, desiccant, with moisture indicator, 100 g list price/quantity total: $110.16 / EA (1 / EA) $0.00 Thomas No. Usually for 60Kg, 70Kg, 130Kg, 200Kg steel drum. In 1887 Morley, in a very long and tedious experiment, determined the weight of water plus phosphorus pentoxide which escaped in an air stream dried over phosphorus … The values which he found for the residual moisture left by each desiccant are, without ex ception, much higher than those found in later investigations.
