Preparation of Trifluoroiodomethane via Vapour-Phase Catalytic Reaction Between Pentafluoroethane and Iodine

Abstract

A new route for preparing CF3I has been developed via a reaction between C2HF5 and I2. The influence of reaction temperature and active components of the catalysts on the amount of CF3I was investigated. The result suggests that the selectivity of the CF3I can be controlled by reaction conditions and active component of catalyst. The process for the formation of CF3I and by-products is also discussed.
