CATALYTIC ACTIVITY VANADIUM OXIDE CATALYSTS MODIFIED BY Ti, Sn, Cr OXIDES IN THE PARTIAL OXIDATION OF 3-METHYLPYRIDINE
Keywords:
oxidation, 3-methylpyridine, nicotinic acid, catalysts, oxideAbstract
The results of catalytic activity of V2O5·МехOy (Ме – Ti, Sn, Cr) binary catalysts and more complex in composition in a wider range of catalytic systems in the partial oxidation of 3-methylpyridine are discussed. It was found that the binary vanadium chromium oxide catalyst showed the greatest activity in this process. Nicotinic acid is obtained with the highest yield (80%) at 330 °C and a molar ratio of reacting substance: 3methylpyridine: oxygen : water vapor = 1:13:25,5.
