Patent AT-E400539-T1: [Translated] METHOD FOR CONTINUOUSLY PRODUCING A PERFLUORALKYLIODIDE TELOMER
The present invention relates to a process for continuously producing a perfluoroalkyl iodide represented by the general formula Rf(CF2CF2)nI, wherein Rf is a C1-6 perfluoroalkyl and n is an integer from 1 to 4, the method comprising continuously supplying a perfluoroalkyl iodide as a telogen represented by the general formula RfI, wherein Rf is as defined above, and tetrafluoroethylene as a taxogen to a tubular reactor packed with a metal catalyst comprising a powdery spherical metal or a sintered metal; and conducting telomerization at a temperature of 60 to 160 DEG C under a pressure of 0.1 to 5 MPa (gauge pressure). According to the present invention, medium-chain perfluoroalkyl iodides can be continuously and efficiently produced with little generation of impurities, such as hydrogen-containing organic compounds and the like.
