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.
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 .
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 .
Acetyl chloride was first prepared in 1852 by French chemist Charles Gerhardt by treating potassium acetate with phosphoryl chloride. [4]Acetyl chloride is produced in the laboratory by the reaction of acetic acid with chlorodehydrating agents such as phosphorus trichloride (PCl 3), phosphorus pentachloride (PCl 5), sulfuryl chloride (SO 2 Cl 2), phosgene, or thionyl chloride (SOCl 2).
It is used to convert primary and secondary alcohols into alkyl chlorides, or carboxylic acids into acyl chlorides, although thionyl chloride generally gives better yields than PCl 3. [ 18 ] Safety
Thionyl chloride [11] ... Low molecular weight acyl chlorides are often lachrymators, and they react violently with water, alcohols, and amines. References
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 of 4.8% from 2024 to 2034.
It is also more expensive than thionyl chloride so it tends to be used on a smaller scale. This reaction involves conversion of N,N-dimethylformamide to the imidoyl chloride derivative (chloromethylene(dimethyl)ammonium ion (CH 3) 2 N + =CHCl), akin to the first stage in the Vilsmeier–Haack reaction. The imidoyl chloride is the active ...
