Gas-phase chlorine-photosensitized oxidation of trichloroethylene

Abstract

The chlorine-photosensitized oxidation of trichloroethylene in the gas phase has been investigated at 363 and 403°K. Dichloroacetyl chloride is the main reaction product and its rate of formation is given by d[C₂HCl₃O]/dt=I_a[O₂]/(k+k′[O₂]). These results can be interpreted by the mechanism of the photochlorination with the following additional steps: [graphic omitted] Rate constants have been estimated.
