Procedure

Perfluorobutyric acid (55 g, 0.26 m) in 25 ml of methanol containing 0.1 g of methane sulfonic acid was refluxed for 16 hours. The product was washed with a sodium carbonate solution and dried over magnesium carbonate. IR analysis showed the following major absorption bands: 2970, 1785, 1310, 1225, 1145, 1085 cm-1.
