A mixture consisting of 775 g of perfluoropentanoyl fluoride, 800 g of anhydrous diglyme, 13.1 g of potassium fluoride, 17.8 g of anhydrous potassium bifluoride and 775 g of hexafluoropropylene was heated in a 3-liter stainless steel pressure vessel under autogeneous pressure at 50° C. for 16 hours. The product was fractionally distilled to give 413 g of 1,1,1,2,4,4,5,5,6,6,7,7,7-tridecafluoro-2-trifluoromethyl-heptan-3-one, having a boiling point of 97° C. and a 99.0% purity as determined by gas chromatography and mass spectroscopy.
