PROCESS FOR PRODUCING FLUOROALKYL IODIDE TELOMER

Page/Page column 3-4, (2011/02/25)
A novel process for producing a fluoroalkyl iodide telomer is provided, which is able to obtain a fluoroalkyl iodide telomer having a desired chain length, efficiently. A fluoroalkyl iodide represented by the general formula RfI (wherein Rf is a C1-10 fluoroalkyl group) and tetrafluoroethylene are used as a telogen and a taxogen, respectively. These compounds are supplied to a distillation apparatus. In a reaction zone located in an intermediate part of the distillation apparatus, the compounds are subjected to a telomerization reaction in the presence of a metal catalyst with heating to generate a fluoroalkyl iodide telomer represented by the general formula Rf(CF2CF2)nI (wherein Rf is the same as defined above and n is an integer of 1-4). Thereafter, a fraction comprising the fluoroalkyl iodide telomer is separated by distillation.
Fluoroalkyl iodide and its production process

Page/Page column 5-6, (2008/06/13)
A process for producing a fluoroalkyl iodide as a telomer Rf(CF2CF2)nI (wherein Rf is a C1-10 fluoroalkyl group, and n is an integer of from 1 to 6) by telomerization from a fluoroalkyl iodide represented by the formula RfI (wherein Rf is as defined above) as a telogen and tetrafluoroethylene (CF2CF2) as a taxogen, which comprises a liquid phase telomerization step of supplying a homogeneous liquid mixture of the telogen and the taxogen from the lower portion of a tubular reactor, moving the mixture from the lower portion towards the upper portion of the reactor in the presence of a radical initiator over a retention time of at least 5 minutes while the reaction system is kept in a liquid phase state is under conditions where no gas-liquid separation will take place, so that the taxogen supplied to the reactor is substantially consumed by the reaction in the reactor, and drawing the reaction product from the upper portion of the reactor.
