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.
