Modification of V2O5 with Ti; Sn; Zr; Nb; and Al oxides improves the activity and selectivity of the vanadium oxide catalyst in vapor-phase oxidation of β-picoline to give nicotinic acid. It is shown that the conversion of β-picoline and the yield of nicotinic acid on two-component V2O5-TiO2; V2O5-SnO2; V2O5-ZtrO2; V2O5-Nb2O5; and V2O5-Al2O3 catalysts may be several times those on the V2O5 catalyst. It was found that; on passing from V2O5 to double-component vanadium-containing catalysts; the proton affinity of active oxygen bonded to vanadium; calculated by the quantum-chemical method; grows simultaneously with the increase in the activity of the catalysts in the oxidation reaction. © 2014 Pleiades Publishing; Ltd;
