YieldReaction ConditionsOperation in experiment
93.4% With sodium carbonate In 5,5-dimethyl-1,3-cyclohexadiene EXAMPLE 6
Into a 500 ml glass reactor equipped with a reflux condenser and a stirrer, 100 g (0.413 mol) of the 3,4,5,6-tetrafluorophthaloyldifluoride separated by distillation from the mixture of Example 2, 43.8 g (0.413 mol) of sodium carbonate and 200 g of xylene were charged, and the mixture was reacted at 130° C. for 1.5 hours with vigorous stirring.
Then, the inorganic substance was removed by filtration, and the residue was separated by distillation to obtain 84.9 g of tetrafluorophthalic anhydride.
The yield was 93.4percent.
