Port Shanghai or Chongqing Phosphorus pentoxide, P2O5 /CAS:1314-56-3, Desiccant, dehydrating agent---- packing weight (Net weight) can be customized accordingly. It exists as a dimer. What you are proposing is a very controlled environment which would likely never exist in real conditions (i.e. Preparation. Phosphorus pentoxide is an acid anhydride that is obtained from phosphoric acid. Search results for phosphorus pentoxide at Sigma-Aldrich. It is highly hygroscopic and is, therefore, used as a dehydrating agent and as a desiccant. 1314-56-3 . Phosphorus pentoxide, desiccant, with moisture indicator, 100 g list price/quantity total: $110.16 / EA (1 / EA) $0.00 Thomas No. 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 … It is an anhydride of phosphoric acid. Compare Products: Select up to 4 products. List of desiccants: 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, Reagent, ACS is the anhydride of phosphoric acid and a powerful dehydrating and desiccant agent. Mfr. Phosphorus pentoxide is normally used as an industrial desiccant and plays a role as an intermediate reactant to turn acid into their anhydride counterparts. 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. This is an empirical formula. *Please select more than one item to compare 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 white crystalline solid which is used as a powerful dehydrating agent. It is a strong desiccant. No. Usually for 60Kg, 70Kg, 130Kg, 200Kg steel drum.
