2.1 g of a mixture of (CF3)2CFOCOCF(CF3)OCF2CF2CF3 and (CF3)2CHOCOCF(CF3)OCF2CF2CF3 obtained in Example 1-2, was charged into a flask together with 0.02 g of NaF powder and heated at 120° C. for 10 hours in an oil bath, while stirring vigorously. At an upper portion of the flask, a reflux condenser having the temperature adjusted at 20° C. and a gas bag were installed in series. After cooling, 1.5 g of a liquid sample and 0.4 g of a gas sample were recovered. The gas sample and the liquid sample were respectively analyzed by GC-MS, whereby from the gas sample, the above-identified compound was confirmed to be the main product, and from the liquid sample, FCOCF(CF3)OCF2CF2CF3 was confirmed to be the main product. The yield of the above-identified compound to (CF3)2CFOCOCF(CF3)OCF2CF2CF3, was 71.2%, as calculated by GC. Further, from the liquid sample, FCOCF(CF3)OCF2CF2CF3 (0.7 g) was obtained.
