Abstract
Phenolic compounds, such as phenol itself, are formed by oxidizing the corresponding aromatic aldehyde precursors, in the vapor phase, with molecular oxygen, the gaseous oxidation product being cooled in the presence of an inert diluent to prevent formation of tarry condensation products. In a particular embodiment a mixture of toluene and benzaldehyde is reacted with oxygen to convert the benzaldehyde to phenol while a portion of the toluene is oxidized to benzaldehyde which is recycled. The products are separated by solvent extraction.
