Optimization of vanadium oxide catalyst for the oxidation of 3-methylpyridine into nicotinic acid
2017
Journal of the Serbian Chemical Society
Upon modification of V 2 O 5 with SnO 2 or ZrO 2 , increase in the activity and selectivity of the vanadium-oxide catalyst in the vapor-phase oxidation of 3-methylpyridine into nicotinic acid were observed. It was shown that the promoting effects of SnO 2 and ZrO 2 were the result of increases under their influence of the proton affinity of the vanadyl oxygen and decreases in the enthalpy of deprotonation of the methyl group of the substrate, connected by a nitrogen atom with the Lewis acidic
