Phosphorus Pentoxide, Reagent, ACS is the anhydride of phosphoric acid and a powerful dehydrating and desiccant agent. C989X80. 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 … phosphorus pentoxide. Phosphorous pentoxide is used as a general very strong desiccant, but still has the viscous phosphorous acid problem. It is a strong desiccant. 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 white crystalline solid is the anhydride of phosphoric acid. List of desiccants: Size 500 g Description Phosphorus pentoxide, desiccant, with moisture … we always expose new phosphorous pentoxide). 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 has several other names such as phosphoric anhydride, phosphorous (V) oxide, diphosphorus pentoxide etc. It reacts with water to form phosphoric acid H3PO4. It is used extensively in organic synthesis as a dehydrating agent. It is highly hygroscopic and is, therefore, used as a dehydrating agent and as a desiccant. 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 … PHOSPHORUS PENTOXIDE CAS No. It is most commonly used to remove humidity that would normally degrade or even destroy products sensitive to moisture. As an ACS grade quality reagent, its chemical spec 1314-56-3 . 79610-500G Pkg. Its molecular formula is P 4 O 10 but it is found as a dimer of P 2 O 5. Compare Products: Select up to 4 products. Usually for 60Kg, 70Kg, 130Kg, 200Kg steel drum. Phosphorus pentoxide, P2O5 /CAS:1314-56-3, Desiccant, dehydrating agent---- packing weight (Net weight) can be customized accordingly. 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. 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 … This is an empirical formula. 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, desiccant, with moisture indicator, 100 g list price/quantity total: $110.16 / EA (1 / EA) $0.00 Thomas No. It is a white crystalline solid which is used as a powerful dehydrating agent. What you are proposing is a very controlled environment which would likely never exist in real conditions (i.e. Mfr. It exists as a dimer. A desiccant is a substance that absorbs water. 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. Preparation.
