The present disclosure provides a process for producing trifluoroiodomethane (CF.sub.3I). 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.

Fluorine gas is introduced to a raw material liquid containing a reaction inducer and a fluorinated hydrocarbon represented by C.sub.pH.sub.qCl.sub.rF.sub.s (in the formula, p is an integer of 3 to 18, q is an integer of 0 to 3, r is an integer of 0 to 9, and s is an integer of 5 to 30) and having no carbon-carbon unsaturated bond to give tetrafluoromethane. The reaction inducer is a halogen-containing carbon compound liquid at room temperature and pressure and is reacted with fluorine gas to induce a reaction of forming tetrafluoromethane from the fluorinated hydrocarbon and the fluorine gas. The reaction inducer is contained at a content of more than 0% by mass and not more than 10% by mass when the total content of the fluorinated hydrocarbon and the reaction inducer contained in the raw material liquid is 100% by mass.
