CATALYTIC PROPERTIES OF V2O5-TiO2 AND V2O5-ZrO2 BINARY SYSTEMS IN THE VAPOR-PHASE OXIDATION OF 3-METHYLPYRIDINE INTO NICOTINIC ACID

Abstract

The results of catalytic activity of V2O5-TiO2 and V2O5-ZrO2 binary catalysts in the partial oxidation of 3-methylpyridine were investigated. It was found that the V-Ti-O catalyst prepared using highly dispersed titanium dioxide particles (200 nm) and V-Zr-O catalyst significantly exceeds both vanadium pentoxide and TiO2 (Rutile) based vanadium-titanium contact by its activity. Nicotinic acid is obtained with the yield of 78-80% at 300 °C and a molar ratio of 3-MP:O2:H2O = 1:13:94.
