Vanadium‐oxide containing catalyst show an outstanding significance in industrial vapor phase oxidation reactions. The partial oxidation of toluene and substituted toluenes, respectively, to their corresponding aldehydes on vanadium‐containing catalysts has been studied. It could be shown that a simultaneous addition of pyridine to the feed leads to an increased aldehyde selectivity at similar conversion compared to runs without co‐feeding of pyridine. Additionally, the desorption of the desired products could be sped up by an increased basicity of the catalyst surface.
