Abstract
The present disclosure provides a process for producing trifluoroiodomethane, the process comprising providing a reactant stream comprising hydrogen iodide and at least one trifluoroacetyl halide selected from the group consisting of trifluoroacetyl chloride, trifluoroacetyl fluoride, trifluoroacetyl bromide, and combinations thereof, reacting the reactant stream in the presence of a first catalyst at a first reaction temperature from about 25° C. to about 400° C. to produce an intermediate product stream comprising trifluoroacetyl iodide, and reacting the intermediate product stream in the presence of a second catalyst at a second reaction temperature from about 200° C. to about 600° C. to produce a final product stream comprising the trifluoroiodomethane.
