실험 절차

Into a 300 ml glass reactor equipped with a reflux condenser and a stirrer, 100 g (0.413 mol) of the 3,3,4,5,6,7-hexafluoro-1-[3H]-isobenzofuranone obtained in Example 2, and 100 ml of acetic acid were charged, and the mixture was reacted for 48 hours under reflux. Then, the reaction mixture was separated by distillation to obtain 79.5 g of tetrafluorophthalic anhydride. The yield was 87.5%.
