실험 절차

Perfluorododecanoic acid 404 g (0.565 mole), bromine 49.4 g (0.309 mole) and Freon 113 (400 ml) were treated with fluorine at 30°-37° C. The reaction mixture was poured into 2N hydrochloric acid (500 ml) and the freon solvent was directly distilled off from the mixture. The residue was cooled and the precipitated solids were collected through known filtration techniques. The precipitate was then distilled under vacuum, to give pure perfluoroundecyl bromide 401 g (95% yield). The bromide has a boiling point of 105° C./2 mm Hg and a melting point of 96°-98° C.
