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 .
Eaton's reagent [1] (10 wt% phosphorus pentoxide solution in methanesulfonic acid) is used as an alternative to polyphosphoric acid in chemical synthesis to promote acylation reactions. References [ edit ]
Di(2-ethylhexyl)phosphoric acid (DEHPA or HDEHP) is an organophosphorus compound with the formula (C 8 H 17 O) 2 PO 2 H. The colorless liquid is a diester of phosphoric acid and 2-ethylhexanol. It is used in the solvent extraction of uranium, vanadium and the rare-earth metals. [1]
Phosphorus oxide can refer to: Phosphorus pentoxide (phosphorus(V) oxide, phosphoric anhydride), P 2 O 5 Phosphorus trioxide (phosphorus(III) oxide, phosphorous anhydride), P 2 O 3
The second number ("P value") is the percentage by weight of phosphorus pentoxide P 2 O 5. The third number ("K value") is the equivalent content of potassium oxide K 2 O. [3] For example, a 15-13-20 fertilizer would contain 15% by weight of nitrogen, 13% by weight of P 2 O 5, 20% by weight of K 2 O, and 52% of some inert ingredient.
Peroxyphosphoric acid is usually produced by treating phosphorus pentoxide and concentrated hydrogen peroxide within an inert solvent like acetonitrile or carbon tetrachloride. [3] [4] P 4 O 10 + 4 H 2 O 2 + 2 H 2 O → 4 H 3 PO 5. One method of preparation is the hydrolysis of potassium of lithium peroxydiphosphate in a strong acid such as ...
