Study of Kinetics on Liquid-Phase Catalytic Oxidation of Toluene

Abstract

The effects of initial concentration,catalyst dosage and catalyst proportion on the result of oxidation of toluene were investigated and kinetic models were figured out. It could be considered that the oxidation rate of toluene wasn’t varied significantly with the change of toluene concentration. The highest yield of benzaldehyde increased with the decrease of toluene concentration and the increase of catalyst dosage. The catalyst proportion had no significant influence on the yield of benzaldehyde and the oxidation of toluene could be inhibited by increasing Co/Mn. There was no significant difference between the activation energies of toluene and benzaldehyde.
