This white crystalline solid is the anhydride of phosphoric acid. As an ACS grade quality reagent, its chemical spec 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. A desiccant is a substance that absorbs water. 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 … List of desiccants: No. PHOSPHORUS PENTOXIDE CAS No. ( Two identical molecules linked together) P4O10 -Molecular formula. It has several other names such as phosphoric anhydride, phosphorous (V) oxide, diphosphorus pentoxide etc. 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 … 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 … Its molecular formula is P 4 O 10 but it is found as a dimer of P 2 O 5. 1314-56-3 . This is an empirical formula. Usually for 60Kg, 70Kg, 130Kg, 200Kg steel drum. Port Shanghai or Chongqing Size 500 g Description Phosphorus pentoxide, desiccant, with moisture … 79610-500G Pkg. Phosphorus pentoxide is an acid anhydride that is obtained from phosphoric acid. C989X80. It is a powerful desiccant and … phosphorus pentoxide. 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, desiccant, with moisture indicator, 100 g list price/quantity total: $110.16 / EA (1 / EA) $0.00 Thomas No. Preparation. It is highly hygroscopic and is, therefore, used as a dehydrating agent and as a desiccant. Compare Products: Select up to 4 products. PRODUCT FEATURES. P2O5 - Diphosphorous Pentoxide. It is a strong desiccant. we always expose new phosphorous pentoxide). It is a white crystalline solid which is used as a powerful dehydrating agent. Phosphorus Pentoxide, Reagent, ACS is the anhydride of phosphoric acid and a powerful dehydrating and desiccant agent. It exists as a dimer. It is an anhydride of phosphoric acid. It is used extensively in organic synthesis as a dehydrating agent. 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. Phosphorus pentoxide is normally used as an industrial desiccant and plays a role as an intermediate reactant to turn acid into their anhydride counterparts. It reacts with water to form phosphoric acid H3PO4. 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. What you are proposing is a very controlled environment which would likely never exist in real conditions (i.e. 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). *Please select more than one item to compare Phosphorous pentoxide is used as a general very strong desiccant, but still has the viscous phosphorous acid problem. It is most commonly used to remove humidity that would normally degrade or even destroy products sensitive to moisture. Mfr. Search results for phosphorus pentoxide at Sigma-Aldrich.
