1. A gas-phase process for producing trifluoroiodomethane, the process comprising:
providing a reactant stream comprising hydrogen iodide and trifluoroacetyl chloride;
reacting the reactant stream in the presence of a first catalyst at a first reaction temperature from about 25° C. to about 120° C. and at a pressure from atmospheric pressure to 300 psig to produce an intermediate product stream comprising trifluoroacetyl iodide; and
reacting the intermediate product stream at a second reaction temperature from about 200° C. to about 600° C. to produce a final product stream comprising the trifluoroiodomethane.
