Abstract

The effect of CO₂ in promoting the aerial oxidation of para-methyl anisole (PMA) to para-methoxy benzaldehyde (PMB) and anisic acid (AnA) over the Co/Mn catalyst system in acetic acid medium has been investigated. Significant enhancement of catalytic activity and selectivity toward PMB and AnA in the presence of CO₂ is observed at the reaction temperature of 393K. UV-visible investigations of the catalyst system reveal that the formation of Co(III) species is enhanced by the help of CO₂, which is probably associated with the CO₂ promotional effect.
