| Abstract: | The influence of molybdenum content on the catalytic performance in the transesterification of dimethyl oxalate (DMO) with
phenol to methyl phenyl oxalate (MPO) and diphenyl oxalate (DPO) was investigated. The results indicated that the MoO3/Al2O3 catalyst with 14 wt% Mo content gave maximal DPO yield with 6.1% and 75.1% DMO conversion. The component, structure and phase
of MoO3/Al2O3 catalysts were characterized by means of X-ray diffraction (XRD), BET specific surface area, temperature-programmed desorption
of ammonia (NH3-TPD), and FTIR analysis of adsorbed pyridine.
