Abstract
The novel process of the invention comprises selectively chlorinating benzoyl chloride in the absence of a solvent to about 7-8% unconverted benzoyl chloride, and recovering the resultant 3-chlorobenzoyl chloride in high yield from the reaction product mixture. A feature of the process is that the ratio of 3-chlorobenzoyl chloride to 2,5-dichlorobenzoyl chloride by-product is maximized.
