実験手順

A suspension of crude 2,3-dichloro-4-trifluoromethoxybenzoyl fluoride (2 g, containing mixed antimony halides) in water was stirred vigorously for 24 hours. The mixture was extracted with dichloromethane and filtered. The organic layer was washed with hydrochloric acid (2M), aqueous sodium chloride solution and extracted into sodium carbonate solution (2M). The aqueous extract was acidified to pH1 and the solid was filtered off and washed with water to give 2,3-dichloro-4-trifluoromethoxybenzoic acid (0.6 g) as a white solid mp 123°-126° C.
