The gas-phase room-temperature oxidation of haloethylenes was studied. In general oxidation has been carried out in five ways: (1) chlorine atom initiation, (2) Hg 6(triplet P) sensitization, (3) reaction with O(triplet P), (4) reaction with O(triplet P) in the presence of O2, and (5) reaction with O3. In the first four systems the major products are the corresponding carbonyl chlorides containing 1 or 2 carbon atoms, and the reaction proceeds by a long-chain free radical process. With O3 a diradical chain is involved which is inhibited by O2. Free radical attack of CH2Cl2 or CH3Cl in the presence of O2 gives carbonyl halides, as does the photolysis of CCl4, CCl3F, and CCl2F2 in the presence of O2 or O3. CCl4 and the chlorofluoromethanes react with O(singlet D) via chlorine atom abstraction in reactions with large rate coefficients which are nearly proportional to the number of chlorine atoms in the chlorofluoromethane. This research was undertaken in order to study the reactions of these compounds in the atmosphere.
