Kontinuierliches Verfahren zur Herstellung von Pentafluorethyliodid

摘要

The invention relates to a continuous method for producing pentafluoroethyl iodine, iodine pentafluoride and tetrafluoroethylene, characterized in that the iodine is dissolved in iodine pentafluoride and the solution obtained is continuously fed to a vertical bubble column (1), which is filled with iodine pentafluoride and which has a tetrafluoroethylene feed line on its lower end, wherein the reaction area is maintained at 85 to 95 DEG C, preferably 90 DEG C and the formed pentafluoroethyl iodide is released in the form of a gas in the head of the reactor (1), is liquefied in a downstream cooled condenser and stored in vessels.
