Abstract: The catalytic activity of ZSM-5 zeolites containing Mg cations in various concentrations has been studied in the alkylation of toluene by ethylene. The concentration of acid centers of different nature in these zeolites was characterized by IR spectroscopy of OH-groups and adsorbed CO. The state of Mg cations in the samples was studied by 15N NMR of the adsorbed N2O. The increase of Mg content was shown to decrease both the concentration of non-protic acid sites of medium strength and the activity of samples, which is related to the increase of association degree of Mg cations in the zeolite.
