Abstract
The present invention provides a process for preparing a perfluoroalkyl bromide characterized by reacting a perfluoroalkyl iodide represented by the formula C.sub.n F.sub.2n+1 I wherein n is an integer of 6 to 10 with bromine in a light-transmitting reactor with exposure to light and heating at 120.degree. to 180.degree. C. while simultaneously removing IBr resulting as a by-product by separation of a layer.
