| Abstract: | Interaction of propene with CoNaX and NaX zeolites and exchange of propene hydrogens with CoNaX zeolite was studied at the temperature of the IR beam and at 300°C by means of IR and MS analysis. In addition, the heats of adsorption were measured. The structure of adsorbed propene complexes was found to be influenced by the presence of Co2+ ions. The mechanism of the exchange is discussed and the properties of the OH groups of HY, HX and CoNaX zeolites are compared.
