TRANSESTERIFICATION OF DIMETHYL OXALATE WITH PHENOL OVER Ti-CONTAINING PHOSPH…

Abstract The transesterification of dimethyl oxalate (DMO) with phenol is studied on various Ti-containing phosphate (Ti-P-O) catalysts. The weak acid-base characteristics of Ti-P-O catalysts are responsible for the high activity and selectivity to methyl phenyl oxalate (MPO) and diphenyl oxalate (DPO).
