Versuchsvorschrift

CF3CF2CF2OCF2CF2CF2OCOCF(CF3)OCF2CF2CF3 (0.8 g) obtained in Example 42 was charged into a flask together with a NaF powder (0.01 g) and heated at 120° C. for 10 hours in an oil bath with vigorous stirring. At an upper portion of the flask, a reflux condenser adjusted to a temperature of 20° C. was installed. After cooling, a liquid sample (0.7 g) was recovered. By GC-MS, it was confirmed that CF3CF(OCF2CF2CF3)COF and the above-identified compound were the main products. The yield was 57.0%.
