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'.
Arsenic trichloride can be prepared by the reaction of arsenic oxide and sulfur monochloride. This method requires simple apparatus and proceeds efficiently: [8] 2 As 2 O 3 + 6 S 2 Cl 2 → 4 AsCl 3 + 3 SO 2 + 9 S. A convenient laboratory method is refluxing arsenic(III) oxide with thionyl chloride: [9] 2 As 2 O 3 + 3 SOCl 2 → 2 AsCl 3 + 3 SO 2
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 ...
Thionyl chloride can be used in place of acetic anhydride to trigger the elimination for forming the electrophilic intermediate and supplying chloride as the nucleophile to give an α-chloro-thioether: [6] Example of the Pummerer rearrangement using thionyl chloride. Other anhydrides and acyl halides can give similar products. Inorganic acids ...
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]
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 ...
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 ...
