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 ]

PCl 3 is a precursor to other phosphorus compounds, undergoing oxidation to phosphorus pentachloride (PCl 5), thiophosphoryl chloride (PSCl 3), or phosphorus oxychloride (POCl 3). PCl 3 as an electrophile
It is produced by replacing the hydrogen bonds between starch chains by stronger, covalent phosphate bonds that are more permanent. It is manufactured by treating starch with sodium tripolyphosphate (STPP) and sodium trimetaphosphate (STMP), or phosphoryl chloride (POCl3). Phosphorylated cross-linked starches is a category of modified food ...
Phosphoryl chloride (POCl 3) is widely used and cited for this purpose. Additionally, SnCl 4 and BF 3 etherate have been used with phenethylamides, while Tf 2 O and polyphosphoric acid (PPA) have been used with phenethylcarbamates.
The Vilsmeier–Haack reaction (also called the Vilsmeier reaction) is the chemical reaction of a substituted formamide (1) with phosphorus oxychloride and an electron-rich arene (3) to produce an aryl aldehyde or ketone (5):
Pyrophosphoric acid. In chemistry, a phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus (P) atom is in the oxidation state +5, and is bonded to four oxygen (O) atoms, one of them through a double bond, arranged as the corners of a tetrahedron.
An inorganic phosphine oxide is phosphoryl chloride (POCl 3). [1] The parent phosphine oxide (H 3 PO) remains rare and obscure. Structure and bonding.
