The present disclosure provides a gas-phase process for producing trifluoroiodomethane, the process comprising providing a reactant stream comprising hydrogen iodide and trifluoroacetyl halide selected from the group consisting of trifluoroacetyl chloride, trifluoroacetyl fluoride, trifluoroacetyl bromide, and combinations thereof, and reacting the reactant stream in the presence of a catalyst at a temperature from about 200° C. to about 600° C. to produce a product stream comprising the trifluoroiodomethane.
Nine perfluoroacylfluorides underwent halogen exchange when treated with anhydrous lithium halides to give acyl chlorides, bromides and iodides in high yields. The temperature dependence of this reaction is described. In the reaction with perfluorodiacyl fluoride, the diacyl halides possessing different acyl halide-groups were also produced. Of the alkaline metal salts used halogen exchange was successful
