Abstract
Preparation of perfluoroalkyl bromides RF-Br, RF denoting a linear or branched perfluoroalkyl radical containing from 2 to 12 carbon atoms. The continuous process according to the invention consists in reacting bromine and a perfluoroalkyl iodide RF-I in the gas phase at a temperature of between 200 and 600 DEG C, it being possible for the Br2/RFI molar ratio to range from 0.1 to 2. The selectivity for RF-Br is virtually complete.
