Abstract
This invention relates to manufacture a normally solid perfluoroalkyl bromide by thermalbromination in the gas phase of a C.sub.10 or greater perfluoroalkyl iodide, bromination is carried out in the presence of a normally liquid perfluoroalkyl bromide. This makes it possible to carry out the post-treatment operations (reduction of iodine, separation, neutralization/washing, and the like) at room temperature.
