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 powerful desiccant and … As an ACS grade quality reagent, its chemical spec Port Shanghai or Chongqing Phosphorous pentoxide is used as a general very strong desiccant, but still has the viscous phosphorous acid problem. It is used extensively in organic synthesis as a dehydrating agent. we always expose new phosphorous pentoxide). ( Two identical molecules linked together) P4O10 -Molecular formula. Mfr. 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. 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 exists as a dimer. What you are proposing is a very controlled environment which would likely never exist in real conditions (i.e. Phosphorus pentoxide, desiccant, with moisture indicator, 100 g list price/quantity total: $110.16 / EA (1 / EA) $0.00 Thomas No. Size 500 g Description Phosphorus pentoxide, desiccant, with moisture … It is an anhydride of phosphoric acid. 1314-56-3 . Usually for 60Kg, 70Kg, 130Kg, 200Kg steel drum. It is most commonly used to remove humidity that would normally degrade or even destroy products sensitive to moisture. 79610-500G Pkg.
