実験手順

Into a clean dry 600 mL Parr reactor equipped with stirrer, heater and thermocouple were added 5.8 g (0.10 mol) of anhydrous potassium fluoride and 108 g of anhydrous diglyme. The contents of the reactor were stirred and cooled with dry ice while 232.5 g (1.02 mol) of n-C3F7COF (approximately 95.0 percent purity) was added to the sealed reactor. The reactor and its contents were then heated, and when a temperature of 72° C. had been reached, 141 g (0.94 mol) of CF2═CFCF3 (hexafluoropropylene) was added at a pressure of 85 psig (5150 torr) over a 3.25 hour time period. During the addition of hexafluoropropylene the temperature of the reactor was increased slowly to 85° C. while maintaining the pressure at less than 90 psig (5400 torr). The pressure at the end of the hexafluoropropylene addition was 40 psig (2800 torr) and did not change over an additional 4-hour hold period. The lower phase was fractionally distilled to give 243.5 grams of 1,1,1,2,4,4,5,5,6,6,6-undecafluoro-2-trifluoromethylhexan-3-one, having a boiling point of 72.5° C. and a purity of 99.9% as determined by gas chromatography. The structure was confirmed by gcms.
