Characterization and reactivity of stannum modified titanium silicalite TS-1 catalysts for transesterification of dimethyl oxalate with phenol

Stannum modified titanium silicalite TS-1 has proved to be an effective catalyst for the transesterification of dimethyl oxalate with phenol to produce methyl phenyl oxalate (MPO) and diphenyl oxalate (DPO), the important intermediates for diphenyl carbonate (DPC) synthesis.
