Hexafluoropropylene → HCID 131723223, compound

Participants

Reaction Steps

To a clean dry 600 mL Parr pressure reactor was charged 53.5 g (0.92 mol) of anhydrous potassium fluoride, 150 g of anhydrous diglyme and 150 g of chlorodifluoroacetic anhydride. With the reactor set at 80° C. and 92 psig (5500 torr), 123 g (0.820 mol) of hexafluoropropylene was charged over a 3 hour period at a tank pressure not exceeding 120 psig (7000 torr). Following reaction for ½ hour at 80° C., the reactor contents were allowed to cool and were distilled to obtain 180.6 g of crude material. Upon fractional distillation, acetic acid/KMnO4 treatment and refractionation of the crude material, 46.1 g (26% of theoretical yield) of (CF3)2CFC(O)CF2Cl, a clear colorless liquid, was obtained having a purity of 98.8% as determined by gas chromatography.
