Abstract:
A continuous process for the preparation of pure pentafluoroethyl iodide from iodine, iodine pertafluoride and tetrafluoroethylene, which comprises dissolving the iodine in a mixture which is separated from the lower end of a vertical bubble column (1) and continuously feeding the resulting solution to said vertical bubble column (1), which is equipped with a level regulator, is filled with iodine pentafluoride and at its lower end has a controllable feed line for tetrafluoroethylene, where the reaction zone is maintained from 85 to 95Â° C., and the pentafluoroethyl iodide formed escapes in gaseous form at the top of the reactor (1), is liquefied in a downstream cooled condenser and is drawn off into storage vessels.
