| Abstract: | A heterogeneous supported catalyst 7.5%Ru/ZrO2·хH2O was prepared by co-precipitation method and characterized by N2 adsorp-tion-desorption,X-ray diffraction,X-ray photoelectron spectroscopy,and high resolution transmission electron microscopy. Its catalytic performance in cinnamaldehyde hydrogenation was investigated. The effects of temperature,hydrogen pressure,and solvent on the activity and selectivity for cinnamyl alcohol were tested. The results showed that the conversion of cinnamaldehyde increased with the increase in temperature and hydrogen pressure,but the product selectivity decreased. The catalyst showed better catalytic performance in a polar solvent than in a non-polar solvent. Using a mixture solvent composed of Et3N and H2O can remarkably raise the activity and the selectivity of the reaction. When the volume ratio of Et3N to H2O was 4,the temperature was 70 °C,and the reaction time was 6 h,the highest conversion(98.0%) and selectivity(85.2%) were obtained. |
