実験手順

In the test apparatus as described in Example I, and following the procedure of Example I, 75 g (0.315 mole) of CF3CF2CCl3, 100 g 65% oleum (0.80 mole as SO3) and 5 g bromine were heated from 25° C. to 60° C. over a 5 hour period. Fractional distillation of the cold trap product, 50 g, gave 42 g (0.23 mole) of CF3CF2COCl, bp 9° C., for a 73% conversion.
