Procedure

The reaction product containing CF3CF2CF2OCF(CF3)COOCF2CF(CF3)OCF2CF2CF3 (83.0 g) obtained in Example 1-2 was charged together with NaF powder (1.1 g) into a flask and heated at 140° C. for 15 hours in an oil bath, while vigorously stirring. At an upper portion of the flask, a liquid sample (81.3 g) was recovered through a reflux condenser having the temperature adjusted to 70° C. A product obtained by distilling the liquid sample for purification was analyzed by GC-MS, whereupon formation of CF3CF2CF2OCF(CF3)COF was confirmed.
