20 Claims

1. A method of producing trifluoroiodomethane (CF₃I), the method comprising:

providing a feedstock comprising trifluoroacetyl iodide (TFAI);

passing the feedstock through at least one column charged with carbonaceous materials to remove at least one of hydrogen iodide (HI), hydrogen triiodide (HI₃) and iodine (I₂) from the feedstock; and

providing the feedstock to a reactor to produce a trifluoroiodomethane product stream.
