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.
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 ...
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 ...
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 ...
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.
They react to produce phosphonates. They require the most heating for the reaction to occur (120 °C - 160 °C is common). This high temperature allows for fractional distillation to be employed in the removal of the alkyl halide produced, though excess of the starting alkyl halide can also be used.
Hexachlorophosphazene is an inorganic compound with the chemical formula (N P Cl 2) 3.The molecule has a cyclic, unsaturated backbone consisting of alternating phosphorus and nitrogen atoms, and can be viewed as a trimer of the hypothetical compound N≡PCl 2 (phosphazyl dichloride).
Triethylphosphite is prepared by treating phosphorus trichloride with ethanol in the presence of a base, typically a tertiary amine: [1] PCl 3 + 3 EtOH + 3 R 3 N → P(OEt) 3 + 3 R 3 NH + 3 Cl −. In the absence of the base, the reaction of ethanol and phosphorus trichloride affords diethylphosphite ((EtO) 2 P(O)H). Of the many related ...
