The cw-CO2 laser-induced gas phase decomposition of hexafluoroacetone sensitized with sulfur hexafluoride (both 0.7-5.2 kPa) affords, besides perfluorinated hydrocarbons and minor amounts of trifluoroacetyl fluoride, carbonyl fluoride the formation of that obeys first-order kinetics and is favored with higher SF6 content.
