The paper gives results of an investigation of the catalytic oxidation of 1,1-dichloroethane over a commercial Cr2O3/Al2O3 catalyst at 500 ppm and 30-500 C. Vinyl chloride was observed as an intermediate in the oxidation process, being formed to significant extents between 230 and 330 C. This suggests HC1 abstraction as the first step in the catalytic oxidation process. Similar experiments on 1,1,1-trichloroethane showed the presence of a 1,1-dichloroethylene intermediate, supporting the HC1 abstraction hypothesis. In both cases, no carbon-chloride bonds were left at 500 C. No significant CO formation was observed, with the material balance on carbon atoms being satisfied by CO2 at 500 C.
