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 occurs in compounds such as thionyl fluoride, SOF 2. Thionyl chloride , SOCl 2 , is a common reagent used in organic synthesis to convert carboxylic acids to acyl chlorides . In organic chemistry , the thionyl group is known as a sulfoxide group or sulfinyl group, and has the general structure RS(=O)R'.
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
Thionyl chloride: an inorganic compound; used in chlorination reactions; converts carboxylic acids to acyl chlorides [6] Thiophenol: an organosulfur compound; the simplest aromatic thiol: Titanium tetrachloride: an intermediate in the production of titanium metal and titanium dioxide Tollens' reagent
The chlorination must be controlled as excess chlorine converts trichloromethanesulfenyl chloride into carbon tetrachloride. Steam distillation separates the trichloromethanesulfenyl chloride and hydrolyzes the disulfur dichloride. Reduction of trichloromethanesulfenyl chloride with, e.g., tin [2] or dihydroanthracene [3] produces thiophosgene:
Thionyl Chloride Market to Reach USD 829.9 Million by 2034, Driven by Expanding Applications in Pesticides, Dyes, and Industrial Chemicals | Future Market Insights NEWARK, Del, Nov. 01, 2024 (GLOBE NEWSWIRE) -- The thionyl chloride market is expected to reach a value of USD 518.7 million in 2024 and USD 829.9 million by 2034, registering a CAGR ...
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]
