実験手順

46.5 g of 3-p-chlorobenzoyl benzonitrile were added to a mixture of 350 cc of water, 350 cc of glacial acetic acid and 350 cc of concentrated sulfuric acid and the resulting mixture was refluxed for 3 hours and 40 minutes. After cooling to 10° C., the mixture was slowly added to water and the precipitate formed was recovered by vacuum filtration, was washed and dried to obtain 48 g of 3-p-chlorobenzoyl benzoic acid melting at 228° C. A sample of the product after crystallization from acetone melted at 234° C.
