実験手順

To the reaction residue from run 3 was added 230 g of p-chlorobenzotrichloride, 97 g of acetic anhydride and 2 g of sulfuric acid (98%). The reaction was carried as previously described to give 136 g (91.2%) of acetyl chloride and 177 g (101%) of p-chlorobenzoyl chloride. The average yield from runs 1-4 was 92.7% for acetyl chloride and 93% for p-chlorobenzoyl chloride.
