Abstract:
1. A process for producing a fluoroalkyl iodide telomer R f (CF 2 CF 2 ) n I , wherein R f is a C 1-10 fluoroalkyl group, and n is an integer of from 1 to 6, comprising: supplying a homogeneous liquid mixture of a fluoroalkyl iodide telogen represented by formula R moving the mixture from the lower portion towards an upper portion of the tubular reactor in the presence of a radical initiator over a retention time of at least 5minutes while a reaction system in the reactor is kept in a liquid phase state under conditions where no gas-liquid separation will take place, so that the taxogen supplied to the tubular reactor is substantially consumed by a telomerization reaction in the tubular reactor; and withdrawing a reaction product from the upper portion of the reactor.
