1. A gas-phase process for producing trifluoroiodomethane, comprising:
providing a reactant stream comprising trifluoroacetyl iodide; and
reacting the reactant stream in the presence of a catalyst at a reaction temperature from about 200° C. to about 600° C. and in the presence of less than 100 ppm of oxygen to produce a product stream comprising the trifluoroiodomethane.
