Method for continuous production of a perfluoroalkyl iodide telomer |
| abstract |
The present invention relates to a process for continuously producing a perfluoroalkyl iodide represented by the general formula R f (CF 2 CF 2 ) n I, wherein R f is a C 1-6 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 R f I, wherein R f 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° C. under a pressure of 0.1 to 5 MPa (gauge pressure). n 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. |
