THE CHLORINE PHOTOSENSITIZED OXIDATION OF HYDROCARBONS AT LOW TEMPERATURES.

Abstract

The oxygen effect on the photochlorination of ethane was studied at 310 K. Due to the extremely long chain of the uninhibited reaction the effect is quite high and can be explained by the reaction of an ethyl chain carrier with the oxygen molecule. The rate constant of this step C2H5 + O2 (yields) C2H5O2 was measured. The rate dependence on concentrations and light intensity are discussed. The chlorine photosensitized oxidation of trichloroethylene and the competition chlorination-oxidation were studied. In the present stage only overall rate equations can be given which can be explained by different mechanisms. In mixtures of chlorine, oxygen and trichloroethylene an after effect appears when the actinic light is cut after a small illumination time. This dark reaction seems to consume only chlorine and trichloroethylene but the explanation of the phenomenon requires more experimental data. These will be obtained by mass-spectrometric measurements performed at the present time. (Author)
