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 ]
DEHPA is prepared through the reaction of phosphorus pentoxide and 2-ethylhexanol: 4 C 8 H 17 OH + P 4 O 10 → 2 [(C 8 H 17 O)PO(OH)] 2 O [(C 8 H 17 O)PO(OH)] 2 O + C 8 H 17 OH → (C 8 H 17 O) 2 PO(OH) + (C 8 H 17 O)PO(OH) 2. These reaction produce a mixture of mono-, di-, and trisubstituted phosphates, from which DEHPA can be isolated based ...
Unprocessed phosphate rock has a concentration of 1.7–8.7% phosphorus by mass (4–20% phosphorus pentoxide). By comparison, the Earth's crust contains 0.1% phosphorus by mass, [84] and vegetation 0.03–0.2%. [85] Although quadrillions of tons of phosphorus exist in the Earth's crust, [86] these are currently not economically extractable.
Elemental phosphorus is distilled out of the furnace and burned with air to produce high-purity phosphorus pentoxide, which is dissolved in water to make phosphoric acid. [22] The thermal process produces phosphoric acid with a very high concentration of P 2 O 5 (about 85%) and a low level of impurities.
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; Phosphorus tetroxide, P 2 O 4; Several other, less common, oxides of phosphorus, including P 4 O 7, P 4 O 9, and P 2 O 6; Gases: Phosphorus monoxide, PO ...
Phosphorus trioxide reacts with water to form phosphorous acid, reflecting the fact that it is the anhydride of that acid. [2] P 4 O 6 + 6 H 2 O → 4 H 3 PO 3. It reacts with hydrogen chloride to form H 3 PO 3 and phosphorus trichloride. P 4 O 6 + 6 HCl → 2 H 3 PO 3 + 2 PCl 3
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 ...
