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 also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs. The list is designated within the Controlled Substances Act [ 1 ] but can be modified by the U.S. Attorney General as illegal manufacturing practices change.
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 .
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 ...
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.
