摘要
The permanent blockade of in situ-formed Bronsted-acid OH groups and an effective lowering of the catalyst acidity during the partial oxidation of toluene to benzaldehyde is demonstrated by an efficient method using a continuous dosing of pyridine to the feed that leads to drastically increased aldehyde selectivities.
