Abstract: Cu-Mn oxides prepared by the coprecipitation method were employed in the liquid-phase oxidation of toluene with molecular oxygen in the absence of solvent. The molar ratio of Cu∶Mn for the best performance of the Cu-Mn oxides in the toluene oxidation is 1∶1. X-ray diffraction characterization shows that the Cu-Mn oxide with a Cu∶Mn ratio of 1∶1 consists of Cu1.5Mn1.5O4.

Key words: toluene, liquid-phase oxidation, copper manganese oxide
