Benzoyl chloride, also known as benzenecarbonyl chloride, is a colourless, fuming liquid, C6H5COCl, with an irritating odour. In the laboratory it may be prepared by distilling benzoic acid (C6H5COOH) with phosphorus pentachloride. On a larger scale it is prepared by chlorinating benzaldehyde.
Benzoyl chloride has a melting point of -1°C and a boiling point of 198°C. The specific gravity is 1.212. It belongs the class of acyl halides.
This substance is used as an intermediate chemical in the preparation of dyes, perfumes, peroxides, pharmaceuticals, and resins. It is also used in photography; as gasoline gum inhibitors, and in the manufacture of synthetic tannins. It was formerly employed as an irritant gas in chemical warfare.
