反応手順
80 g of 80% strength by weight 2,3,5,6-tetrafluoroterephthalic acid (containing 8% by weight of sulfuric acid and 12% by weight of water) were mixed with 300 g of water in a 0.6 l enamelled autoclave and heated for 40 hours at 130° C. After cooling to 20° C. and depressurizing, the suspension then present was filtered, washed with 60 g of water and the white solid was dried. 42 g of 2,3,5,6-tetrafluorobenzoic acid having a content of 98% by weight and a melting point of 151° C. were obtained.
