Abstract
A process is described for the preparation of aromatic aldehydes such as benzaldehyde or substituted benzaldehydes involving the vapor phase oxidation of aralkyl compounds such as toluene or substituted toluenes, respectively, at temperatures of less than about 250.degree.C. in the presence of a catalyst composition containing phosphoric acid and a catalytically effective amount of palladium metal. The aromatic aldehydes are produced in a single reaction step.
