The cw CO2laser-induced decomposition of hexafluoroacetone sensitized with boron trichloride (total pressure 5.3-8.0 kPa) yields along with perfluorinated hydrocarbons trifluoroacetyl fluoride, carbon monoxide and carbonyl fluoride. The same carbonyl compounds are also formed by conventional thermal decomposition of hexafluoroacetone on tungsten filament at temperatures 950-2 100°C but their distribution during reaction progress is different. Features of both reactions are discussed.
