실험 절차

A mixture of trichloroanisole (0.1 g mol; 21.15 g) and 1,2,4,5-tetrachlorobenzene (10 g) in xylene (80 ml) was heated at 80° C. with aluminium trichloride (0.05 mole; 6.65 g) for five hours. Trichlorophenol was isolated in 97% yield (based on trichloroanisole) as described in Example I below. Unchanged tetrachlorobenzene, together with xylene self condensation product (total 13.25 g) was isolated from the neutral product fraction after solvent removal.
