Conditions

Temperature: 40 °C

Procedure

CF3CF2COO(CF2)2O(CF2)2OCF(CF3)CF2OCOCF2CF3 (5.1 g) obtained in Example 5-4 was charged together with 0.09 g of KF powder into a flask and heated at 40° C. for 2 hours in an oil bath while vigorously stirring. At an upper portion of the flask, a reflux condenser adjusted to a temperature of 20° C. and a gas-collecting fluororesin container were installed in series. After cooling, a liquid sample (3.2 g) and a gaseous sample (1.6 g) were recovered. By GC-MS, it was confirmed that the gaseous sample contained CF3CF2COF as the main product, and the liquid sample contained the above-identified compound as the main product. Further, the 19F-NMR yield of the above-identified compound contained in the product was 92%.
