반응 단계
Into a 200 ml glass reactor equipped with a reflux condenser and a stirrer, 50 g (0.207 mol) of the mixture (1:1) of the 3,4,5,6-tetrafluorophthaloyldifluoride and the 3,3,4,5,6,7-hexafluoro-1-[3H]-isobenzofuranone of Example 2, and 50 ml of trifluoroacetic acid were charged, and the mixture was refluxed for 72 hours with vigorous stirring. Then, the reaction mixture was separated by distillation to obtain 29.6 g of tetrafluorophthalic anhydride. The yield was 65%.
