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