실험 절차

A reaction flask was charged with 1.97 g of 4-chlorotetrahydrophthalic anhydride and 0.98 g of activated carbon (DARCO KB-60). 1,2,4-trichlorobenzene (15 mL) was added and the reaction heated to 190° C. Analysis of the reaction mixture showed the formation of 4-chlorophthalic anhydride, with no phthalic anhydride formed at all.
