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).
In IUPAC nomenclature, an acetyl group is called an ethanoyl group. An acetyl group contains a methyl group (−CH 3) that is single-bonded to a carbonyl (C=O), making it an acyl group. The carbonyl center of an acyl radical has one non-bonded electron with which it forms a chemical bond to the remainder (denoted with the letter R) of the molecule.
Hydrated chloroacetaldehyde is produced by the chlorination of aqueous vinyl chloride: ClCH=CH 2 + Cl 2 + H 2 O → ClCH 2 CHO + 2 HCl. It can also be prepared from vinyl acetate [5] or by careful chlorination of acetaldehyde. [1] The related bromoacetaldehyde is prepared via bromination of vinyl acetate. It also rapidly forms an acetals in the ...
For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm −1. The simplest stable acyl chloride is acetyl chloride; formyl chloride is not stable at room temperature, although it can be prepared at –60 °C or below. [2] [3]
Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant .

Some Democrats are dismissing the forthcoming DOGE push to cut wasteful government spending. Others in the party aren't totally writing off what Elon Musk and Vivek Ramaswamy are selling.
Chloroacetyl chloride is bifunctional—the acyl chloride easily forms esters [4] and amides, while the other end of the molecule is able to form other linkages, e.g. with amines. The use of chloroacetyl chloride in the synthesis of lidocaine is illustrative: [ 5 ]
