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.
Phosgene is an organic chemical compound with the formula COCl 2. It is a toxic, colorless gas; ... thionyl chloride is ... The synthesis of isocyanates from ...
It will react with thionyl chloride to produce methylphosphonic acid dichloride, which is used in the production of sarin and soman nerve agents. Various amines can be used to catalyse this process. [3] It can be used as a sarin-simulant for the calibration of organophosphorus detectors.
All are easily hydrolyzed. Indeed, thionyl chloride can be used as a dehydration agent as the water molecules are converted into gaseous products, leaving behind the anhydrous solid chloride. [11] MgCl 2 ·6H 2 O + 6 SOCl 2 → MgCl 2 + 6 SO 2 + 12 HCl. Selenium and tellurium form similar compounds and also the oxo-bridged species F 5 AOAF 5 (A ...
The von Braun amide degradation is the chemical reaction of a monosubstituted amide with phosphorus pentachloride or thionyl chloride to give a nitrile and an organohalide. [1] It is named after Julius Jacob von Braun, who first reported the reaction. [2] [3] The von Braun amide degradation
Methylphosphonyl dichloride is produced by oxidation of methyldichlorophosphine, with sulfuryl chloride: [3]. CH 3 PCl 2 + SO 2 Cl 2 → CH 3 P(O)Cl 2 + SOCl 2. It can also be produced from a range of methylphosphonates (e.g. dimethyl methylphosphonate) via chlorination with thionyl chloride.
The Beckmann rearrangement is often catalyzed by acid; however, other reagents have been known to promote the rearrangement. These include tosyl chloride, thionyl chloride, phosphorus pentachloride, phosphorus pentoxide, triethylamine, sodium hydroxide, trimethylsilyl iodide among others. [3]
A typical representative organic reaction displaying this mechanism is the chlorination of alcohols with thionyl chloride, or the decomposition of alkyl chloroformates, the main feature is retention of stereochemical configuration. Some examples for this reaction were reported by Edward S. Lewis and Charles E. Boozer in 1952. [2]
