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'.
For this application, thionyl chloride is commonly used instead of phosgene. ... The US Chemical Safety Board released a video detailing the accident. [42]
Arsenic trichloride is an inorganic compound with the formula AsCl 3, also known as arsenous chloride or butter of arsenic. This poisonous oil is colourless, although impure samples may appear yellow.
3,5-Dinitrobenzoyl chloride (C 7 H 3 ClN 2 O 5) is an organic compound with a melting point of 68–69 °C. [1] It is the acyl chloride of 3,5-dinitrobenzoic acid and like it is mainly used in the analysis of organic substances by derivatization .
Thionyl chloride is a crucial chemical intermediate in pharmaceutical synthesis, with the pharmaceutical industry's growth and demand for new drugs driving its consumption. The agricultural industry's need for pesticides and agrochemicals also fuels the demand for thionyl chloride, as it plays a significant role in producing these compounds.
A solution of lithium tetrachloroaluminate in thionyl chloride is the liquid cathode and electrolyte in those baterries, e.g. the lithium-thionyl chloride cell. Another cathode-electrolyte formulation is lithium tetrachloroaluminate + thionyl chloride + sulfur dioxide + bromine.
Dimethyl methylphosphonate is a schedule 2 chemical as it may be used in the production of chemical weapons. 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.
