Kinetics of the β-picoline oxidation to nicotinic acid over vanadia-titania catalyst. 2. Effect of dioxygen and β-picoline

Kinetics of oxidation of β-picoline to nicotinic acid over vanadia-titania catalyst. 4. Kinetic model

“…The other products are pyridine-3-carbaldehyde (PA), pyridine-3-nitrile (PN), CO and CО 2 (СО х ) [1, [3][4][5]. In a number of cases, the formation of small amounts of pyridine was observed as well.…”

“…All the components of the reaction mixture influence the formation of the selective oxidation products. The dependencies of the product formation rates on the concentrations of βP, oxygen and water are described by saturation curves [3][4][5].…”

“…The kinetics of the β-picoline (βP) oxidation was studied over a catalyst with the composition of 20% V 2 O 5 / 80% TiO 2 (wt.%) [3][4][5]. The catalyst grain was a _________________________ * Corresponding author.…”

“…The experiment was carried out in a differential reactor in flow and flow-circulation installations with gas-chromatographic analysis of the components of the reaction mixture. The details of the experiments, analysis and calculation procedures were described earlier [3][4][5].…”

“…The investigation of the observed kinetics over the grain of an industrial catalyst and the development of a full kinetic model are of great interest considering the prospects for the industrial production of nicotinic acid by this method. This paper, which concludes a series of the studies devoted to the kinetics of this process [3][4][5], reports on the construction of a corresponding kinetic model.…”
