Tracer study of complete oxidation complexes in the oxidative dehydrogenation of butylene

A tracer technique using divinyl-¹⁴C was used to determine the butylene and divinyl contents in the surface complexes of complete oxidation during the oxidative dehydrogenation of butylenes over Bi–Mo, Fe–Sb and Fe₂O₃ catalysts. The rate of decomposition of the surface complexes was found to be independent of their relative butylene and divinyl content.
