Procedure
CF3CF2COOCF2CF2CF3 (20 g) obtained in Example 5 and chlorotrifluoroethylene oligomer (120 g) were charged into a 200 ml autoclave made of nickel and equipped with a reflux condenser and heated to 200° C. The reflux condenser was cooled by circulating cooling water, and when the pressure became at least 0.1 MPa, the gas was purged while maintaining the pressure to recover a gaseous sample (15 g). By GC-MS, it was confirmed that CF3CF2COF was the main product. The GC yield was 90%.
