Synthesis of perfluoroalkyl iodides |
摘要 |
The invention relates to a continuous process for the preparation of perfluoroalkyl iodides by thermal telomerization, in the gas phase, of tetrafluoroethylene with pentafluoroethyl iodide or heptafluoroisopropyl iodide in a tubular reactor. To improve the selectivity for a telomer of the desired extent, the telomers of lesser extent are recycled to at least one point in the reactor, which is situated between one-twentieth and three-quarters the length of the tube.
