Method for preparing perfluorobutyl iodide

The invention discloses a method for preparing perfluorobutyl iodide. The method comprises the steps that aluminate ionic liquid is adopted as a solvent and a catalyst, decarboxylation and iodinationof perfluorovaleric acid are conducted under the same condition, and the yield of the perfluorovaleric acid is up to 92% or above. In the process, the step of perfluorovaleric acid alkalization is omitted, conventional liquid alkali is prevented from being used, emission of wastewater and waste salt is reduced, the device cost is reduced, and industrial production is facilitated.

METHOD FOR CONTINUOUS PRODUCTION OF A PERFLUOROALKYL IODIDE 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°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.
