Phosphorus trichloride is an inorganic compound with the chemical formula PCl 3. A colorless liquid when pure, it is an important industrial chemical , being used for the manufacture of phosphites and other organophosphorus compounds .
Phosphorus trichloride is a major industrial chemical and widely used starting material for phosphorus chemistry. Phosphorus tribromide is used in organic chemistry to convert alcohols to alkyl bromides and carboxylic acids to acyl bromides ( e.g. in the Hell-Volhard-Zelinsky reaction ).
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 ]
Phosphite esters are typically prepared by treating phosphorus trichloride with an alcohol. For alkyl alcohols the displaced chloride ion can attack the phosphite, causing dealkylation to give a dialkylphosphite and an organochlorine compound. [1] [2] The overall reaction is as follows: PCl 3 + 3 C 2 H 5 OH → (C 2 H 5 O) 2 P(O)H + 2 HCl + C 2 ...
Trichloride may refer to: The trichloride ion, a polyhalogen ion; Actinium trichloride, AcCl 3; ... Phosphorus trichloride, PCl 3, a yellow solid; Plutonium ...
Thiophosphoryl chloride is an inorganic compound with the chemical formula P S Cl 3. [5] It is a colorless pungent smelling liquid that fumes in air. It is synthesized from phosphorus chloride and used to thiophosphorylate organic compounds, such as to produce insecticides.
Diphosphorus tetrachloride is an inorganic compound with a chemical formula P 2 Cl 4 ... the compound degrades to give phosphorus trichloride and an ill-defined ...
Chlorodiphenylphosphine is an organophosphorus compound with the formula (C 6 H 5) 2 PCl, abbreviated Ph 2 PCl. It is a colourless oily liquid with a pungent odor that is often described as being garlic-like and detectable even in the ppb range. It is useful reagent for introducing the Ph 2 P group into molecules, which includes many ligands. [2]
