摘要
Abstract
Ru/ZrO2·xH2O was prepared by co-precipitation method and 2,2-difluoroethanol was obtained by catalytic hydrogenation of methyl difluoroacetate over the catalyst Ru/ZrO2·xH2O in liquid phase. The flesh catalyst and catalyst after reaction were characterized by XRD. Effects of solvent, stirring rate, reaction time, pressure and temperature were investigated. The results showed that: when solvent was water, stirring rate was 1 000 r/min, reaction time was 5 h, reaction pressure was 2.8 MPa, reaction tempreture was 140~C, the conversion of methyl difluoroacetate was 100%, yield of 2,2-difluoroethanol were 51%.关键词
