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 .
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 general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and n + 2 / 2 . Pyrophosphate anion. Trimethyl orthophosphate.
Phosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula P O Cl 3. It hydrolyses in moist air releasing phosphoric acid and fumes of hydrogen chloride. It is manufactured industrially on a large scale from phosphorus trichloride and oxygen or phosphorus pentoxide. [4] It is mainly used to make ...
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]
Its chemical composition by weight is: silica (SiO 2) 43–47%, calcium oxide (CaO) 22.5–26.5%, phosphorus pentoxide (P 2 O 5) 5–7% and sodium oxide (Na 2 O) 22.5–26.5%. [ 2 ] Glasses are non-crystalline disordered solids that are commonly composed of silica-based materials with other minor additives.
Typical bone ash consists of about 55.82% calcium oxide, 42.39% phosphorus pentoxide, and 1.79% water. [1] The exact composition of these compounds varies depending upon the type of bones being used, but generally the formula for bone ash is Ca 5 (OH)(PO 4) 3. Bone ash usually has a density around 3.10 g/mL and a melting point of 1670 °C (3038 ...
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 + 4H 2 O 2 + 2H 2 O → 4H 3 PO 5. One method of preparation is the hydrolysis of potassium of lithium peroxydiphosphate in a strong acid such as ...
