Abstract: The present disclosure provides a process for producing trifluoroiodomethane (CF3I). The process includes providing vapor-phase reactants including trifluoroacetyl halide, hydrogen, and iodine, heating the vapor-phase reactants, and reacting the heated vapor-phase reactants in the presence of a catalyst to produce trifluoroiodomethane. The catalyst includes a transition metal.

Abstract: The present disclosure provides a method for purifying trifluoroiodomethane. The method includes providing a process stream comprising trifluoroiodomethane, organic impurities, and acid impurities; reacting the process stream with a basic aqueous solution, the basic aqueous solution comprising water and at least one base selected from the group of an alkali metal carbonate and an alkali metal hydroxide; and separating at least some of the organic impurities from the process stream.
