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. It is toxic and reacts readily with water to release hydrogen chloride.
In water PSCl 3 reacts, and contingent on the reaction conditions, produces either phosphoric acid, hydrogen sulfide, and hydrochloric acid or dichlorothiophosphoric acid and hydrochloric acid. [9] PSCl 3 + 4 H 2 O → H 3 PO 4 + H 2 S + 3 HCl PSCl 3 + H 2 O → HO−P(=S)Cl 2 + HCl. An intermediate in this process appears to be tetraphosphorus ...
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 ...
Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.
Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula P H 3, classed as a pnictogen hydride.Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P 2 H 4).
Thionyl chloride is an inorganic compound with the chemical formula SOCl 2.It is a moderately volatile, colourless liquid with an unpleasant acrid odour.Thionyl chloride is primarily used as a chlorinating reagent, with approximately 45,000 tonnes (50,000 short tons) per year being produced during the early 1990s, [5] but is occasionally also used as a solvent.
It is hydrolyzed by hot water to release ammonia and hypochlorous acid. NCl 3 + 3 H 2 O → NH 3 + 3 HOCl. Concentrated samples of NCl 3 can explode to give N 2 and chlorine gas. [citation needed] 2 NCl 3 → N 2 + 3 Cl 2. In the presence of aluminium trichloride, NCl 3 react with some branch hydrocarbon to produce, after a hydrolysis step ...
Chlorodiphenylphosphine is produced on a commercial scale from benzene and phosphorus trichloride (PCl 3). Benzene reacts with phosphorus trichloride at extreme temperatures around 600 °C to give dichlorophenylphosphine (PhPCl 2) and HCl. Redistribution of PhPCl 2 in the gas phase at high temperatures results in chlorodiphenylphosphine. [2] [3]
