실험 절차
The same reactor as in Example 1 was used. Into the flask was placed 200 ml (747 mM) of perfluorooctyl iodide (PFOI), which was then heated at 160° C. and irradiated with a 400-W high-pressure mercury lamp. After the reaction mixture started to reflux, 54.5 ml (1.07M) of bromine was added dropwise to the mixture at a rate of 0.4 ml/min over a period of about 2 hours. The resulting IBr was drawn off at a suitable time through the IBr withdrawing Dimroth condenser. The reaction was continued for 3 hours, and the reaction mixture was thereafter cooled and washed with a 5% aqueous solution (200 ml) of sodium hydroxide, giving 349.0 g (93.6% in yield) of perfluorooctyl bromide.
