| 1 | Preparation of Diphenyl Oxalate from Transesterification of Dimethyl Oxalate with Phenol over TS-1 Catalyst显示文摘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. | Xin Bin MA*, Sheng Ping WANG, Hong Li GUO, Gen Hui XU State Key Laboratory of C1 Chemistry and Technology, School of Chemical Engineering and Technology, Tianjin University, Tianjin 300072 | 2003 | Chinese Chemical Letters2003，14，5： | 2 |
