Participants

Reaction Steps

The reaction was carried out in the same equipment and in a similar manner to the procedure of Example 7 above, but using the following materials: spray-dried potassium fluoride (6 kg, 103.1 mole), anhydrous dimethyl formamide (25.1 kg), perfluorobutyryl fluoride (58% purity, 25.1 kg, 67.3 mole), and dimethyl sulfate (12.0 kg, 95.1 mole). 22.6 kg of product was obtained, which was 63.2% C4F9COH3 (b.=58-60° C.). The product identity was confirmed by GCMS and by 1H and 19F NMR.
