Some chloroacetyl chloride is also used to produce phenacyl chloride, another chemical intermediate, also used as a tear gas. [3] Phenacyl chloride is synthesized in a Friedel-Crafts acylation of benzene, with an aluminium chloride catalyst: [6] With anisole, it is used for the synthesis of venlafaxine.
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 organic chemistry, an acyl chloride (or acid chloride) is an organic compound with the functional group −C(=O)Cl. Their formula is usually written R−COCl, where R is a side chain. They are reactive derivatives of carboxylic acids (R−C(=O)OH). A specific example of an acyl chloride is acetyl chloride, CH 3 COCl.
These may be metal salts containing chloride ion such as sodium chloride, or more covalent chlorides of metals or nonmetals such as titanium(IV) chloride or thionyl chloride. See also [ edit ]
Unlike typical acid chlorides, which are often prepared from the associated carboxylic acid, dichloroacetyl chloride is not prepared from dichloroacetic acid. Instead, industrial routes include oxidation of 1,1,2-trichloroethane, hydrolysis of pentachloroethane, and the carboxylation of chloroform: [4] CHCl 2 CH 2 Cl + O 2 → CHCl 2 COCl + H 2 O
Benzoyl chloride, also known as benzenecarbonyl chloride, is an organochlorine compound with the formula C 7 H 5 ClO. It is a colourless, fuming liquid with an irritating odour, and consists of a benzene ring ( C 6 H 6 ) with an acyl chloride ( −C(=O)Cl ) substituent .
