Abstract : In recent years as a result of study of the reaction of oxidation of propylene into acrolein by the method of tracers, a dissociative mechanism of adsorption of propylene on copper and bismuth-molybdenum catalyst was offered with the breaking away of the hydrogen atom from the methyl group and formation of allyl radical (or more correctly allyl complex with catalyst), which later under the influence of oxygen is oxidized to acrolein. Clarification of the mechanism of these reactions is the subject of the present work, the purpose of which was to study propylene sorption by infrared spectroscopy. As adsorbents cupric and cuprous oxides were selected. The obtained results agree with the previous data on the dissociative mechanism of adsorption of propylene on cuprous oxide, and also confirm the assumption on the adsorption of propylene on cupric oxide chiefly with respect to the double bond.
