    Abstract: Provided is a method for preparing perfluoroalkyl iodide through a vapor phase continuous catalytic process, which is performed under mild conditions to avoid explosion or other dangerous factors, gives a high yield of a desired product, and is amenable to mass production. The method for preparing perfluoroalkyl iodide comprises the step of performing telomerization of tetrafluoroethylene(C2F4) with perfluoroethyl iodide(C2F5I) in the presence of a catalyst. The telomerization is performed through a vapor phase continuous catalytic process in a fixed-bed tube shaped reactor, in which an alumina-supported transition metal catalyst is packed, by introducing tetrafluoroethylene and perfluoroethyl iodide in a vapor phase. The telomerization is performed under ambient pressure at a temperature of 250-450 deg.C.
