Abstract
A novel process for producing iodotrifluoromethane is provided which comprises reacting trifluoromethane with iodine in the presence of oxygen by use of a catalyst containing a salt of a metal supported by a carbonaceous carrier. In this process, the catalyst life is lengthened greatly, the by-product is decreased, and the unreacted iodine can be recovered efficiently as high-purity iodine to be recycled without purification.
Claims6
A process for producing iodotrifluoromethane, comprising reacting trifluoromethane with iodine in the presence of oxygen by use of a catalyst containing a salt of an alkali metal, an alkaline earth metal or combinations thereof, supported by a carbonaceous carrier, wherein the oxygen is fed in a volume ratio to the trifluoromethane (oxygen/trifluoromethane) ranging from 0.01 to 1.0.
