Abstract
Ethylene and deuterated ethylene epoxidation on silver was studied on chlorine-modified catalyst in order to elucidate the mechanism by which the epoxidation of deuterated ethylene proceeds at a higher rate than that of ethylene, as was reported by Cant and Hall. The isotope effect strongly decreased with increasing selectivity as a result of the chlorinate surface and it increased with increasing temperature. The rate of epoxide formation increased and that of carbon dioxide formation decreased when ethylene was replaced by deuterated ethylene, in agreement with the results by Cant and Hall. Kinetic studies suggested that the rate of oxygen adsorption was rate-limiting. The results indicated that the surface oxygen species responsible for epoxide formation can also react with ethylene to give an intermediate ethylene species which undergoes total combustion.
