Oxidation of toluene to benzaldehyde over VSb0.8Ti0.2O4. Effect of the operating conditions

In the present work, the kinetic toluene oxidation on VSb0.8Ti0.2O4 based catalyst was studied. A reaction network, which involves three steps: the partial oxidation of toluene to benzaldehyde, a consecutive oxidation of benzaldehyde to carbon oxides and a parallel oxidation of toluene to carbon oxi...
