実験手順

After mixing 110 g (0.5 mol) of tetrafluorophthalic anhydride and 150 ml of water, the mixture was refluxed for about one hour. After cooling the reaction mixture, crystals deposited were collected by filtration and dried to provide 97.6 g (yield 82%) of tetrafluorophthalic acid as white crystals. If necessary, the crystals could be further purified by recrystallization from an aqueous 6N hydrochloric acid solution.
