Benzoyl chloride, also known as benzenecarbonyl chloride, is an organochlorine compound with the formula C6H5COCl. It is a colourless, fuming liquid with an irritating odour. It is mainly useful for the production of peroxides but is generally useful in other areas such as in the preparation of dyes, perfumes, pharmaceuticals, and resins.
==Preparation==
Benzoyl chloride is produced from benzotrichloride using either water or benzoic acid:〔Takao Maki, Kazuo Takeda “Benzoic Acid and Derivatives” Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. 〕
:C6H5CCl3 + H2O → C6H5COCl + 2 HCl
:C6H5CCl3 + C6H5CO2H → 2 C6H5COCl + HCl
As for other acyl chlorides, it can be generated from the parent acid and other chlorinating agents phosphorus pentachloride or thionyl chloride. It was first prepared by treatment of benzoic acid with chlorine.
An early method for production of benzoyl chloride involved chlorination of benzyl alcohol.〔(US1851832 ), 29 March 1932〕
