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.
Aside from the widely used reactions described above, phosgene is also used to produce acyl chlorides from carboxylic acids: R−C(=O)−OH + COCl 2 → R−C(=O)−Cl + HCl + CO 2. For this application, thionyl chloride is commonly used instead of phosgene.
In oxychlorination, hydrogen chloride instead of the more expensive chlorine is used for the same purpose: CH 2 =CH 2 + 2 HCl + 1 ⁄ 2 O 2 → ClCH 2 CH 2 Cl + H 2 O. Secondary and tertiary alcohols react with hydrogen chloride to give the corresponding chlorides. In the laboratory, the related reaction involving zinc chloride in concentrated ...
The thionyl group is SO, a sulfur atom plus an oxygen atom. 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 .
a mineral acid with many industrial uses; commonly used in the laboratory preparation of hydrogen halides Phosphorus pentachloride: one of the most important phosphorus chlorides; a chlorinating reagent. Also used as a dehydrating agent for oximes which turn them into nitriles. Phosphorus tribromide: used for the conversion of alcohols to alkyl ...
This growth is attributed to the increasing demand and popularity of industrial thionyl chloride due to its use in pesticides, dyes, chemicals, and various global applications. Thionyl chloride is a crucial chemical intermediate in pharmaceutical synthesis, with the pharmaceutical industry's growth and demand for new drugs driving its ...
In the laboratory, acyl chlorides are generally prepared by treating carboxylic acids with thionyl chloride (SOCl 2). [8] The reaction is catalyzed by dimethylformamide and other additives. [ 9 ] [ 10 ]
Unlike traditional cocktails made that use a spirit as a base, most nonalcoholic drinks are water-based or contain a high quantity of water through ingredients like fruit juices or teas.
