摘要
The carboxylic functionalized ionic liquid was immobilized on the molecular sieve(MCM-22)and then applied in the catalytic synthe-sis of ethyl methyl carbonate(EMC)via transesterification of dimethyl carbonate(DMC)with ethanol.Combined characterization results of FT-IR,XRD and TG suggest that the ILs had been immobilized on molecular sieve MCM-22.The influences of reaction temperature,time,and the mass ratio of MCM-22-CPTES-MIL/Ca O have also been investigated in detail.The catalytic tests demonstrated that MCM-22-CPTES-MIL/Ca O could catalyze the transesterification of DMC and ethanol with high efficiency,superior to those results of the heterogeneous catalysts reported previously.
