Diphenyl oxalate was synthesized from transesterification of dimethyl oxalate with phenol over TS-1( 2.5 wt% Ti ) catalyst.TS-1 catalyst, as a heterogeneous catalyst, showed excellent selectivity of diphenyl oxalate and methylphenyl oxalate compared with other homogeneous catalysts.Lewis acid sites on TS-1 catalyst were the active sites for transesterification of dimethyl oxalate with phenol.The high selectivity was closely related to the weak acid sites over TS-1.
