Decomposition of isopropanol and cumene cracking have been studied on mixed transition oxide systems, catalysts for selective oxidation, of different mode of arrangement of the two oxide components. Bismuth-iron and cobalt-tellurium molybdates were taken as examples of monophasic systems, V2O5 - TiO2 and SnO2 - SbO4 as examples of multiphasic ones. The change of acidic properties with the different mode of dispersion of the two oxides has been shown in the two latter cases, and the possibility of applying the acidic reactions to characterization of this parameter is discussed. Correlation between acidic properties, measured by rate of these reactions, and selectivity to partial oxidation products are considered.
