Conclusions 1. The introduction of vanadium and molybdenum oxides into MgO gives rise to the formation of acid centers which bond with adsorbed methylpyrazine and 4-methylpyrimidine through the ring nitrogen atom. 2. Increasing the temperature changes the state of these active centers and thereby increases the strength of coordinational bonding of the methylpyrazine and 4-methylpyrimidine with the surface of the vanadium and molybdenum oxides on MgO. Similar effects are not observed in the interaction of these diazines with the γ-Al2O3 surface. 3. The interaction of oxygen with methylpyrazine and 4-methylpyrimidine adsorbed on vanadium and molybdenum oxides supported by MgO gives rise to the formation of surface heterocyclic carbonyl compounds.
