Procedure: To a 1 L monel metal reactor charged with 18 g (0.43 mol) of NaF, 12.1 g (0.112 mol) of CH2(COF)2 was charged with condensation, and thereto, 0.1 g/h of fluorine gas was blown gradually while controlling increasing the inner pressure with keeping the reactor at 0° C., and the reaction was conducted. When the total pressure increased by the product reached to 0.44 atm, the blowing of fluorine gas was finshed. The reaction product was separated and purified, and 1.7 g (0.0118 mol) of CF2(COF)2 was obtained. It was confirmed with FT-IR and 19F-NMR that the resulting compound was CF2(COF)2. The yield thereof was 10%. was charged with condensation while controlling increasing the inner pressure at 0° C. When the total pressure increased by the product The reaction product was separated purified

The mixture was stirred and heated at 80° to 110° for about 24 h. Then, 187 g (65% yield) of crude difluoromalonyl fluoride was collected which, after trap-to-trap distillation, was analyzed by NMR at -30°.
