| 摘 要： | The effect of transition metals (Cr, Mn, Fe, Co and Ni) on the hydrogenation of cinnamaldehyde over Pt/ZrO2 catalysts was studied in ethanol at 343K under 2.0MPa H2 pressure. PtCo/ZrO2 and PtFe/ZrO2 catalysts exhibit high selectivity and activity of hydrogenation for C=O (93.8% at 87.3% conversion and 83.6% at 88.6% conversion, respectively), and PtNi/ZrO2 exhibits high selectivity of hydrogenation for C=C (64.3% at 70.6% conversion). In the presence of trace H2O and NaOH, over the PtNi/ZrO2 (0.4wt%Ni) catalyst the selectivity to hydrocinnamalde hydereaches 90.6% and the conversion of cinnamaldehyde is 90.5%.

| Abstract: | The effect of transition metals (Cr, Mn, Fe, Co and Ni) on the hydrogenation ofcinnamaldehyde over Pt/ZrO_2 catalysts was studied in ethanol at 343K under 2.0MPa H_2 pressure.PtCo/ZrO_2 and PtFe/ZrO_2 catalysts exhibit high selectivity and activity of hydrogenation for C=O(93.8% at 87.3% conversion and 83.6% at 88.6% conversion, respectively), and PtNi/ZrO_2 exhibitshigh selectivity of hydrogenation for C=C (64.3% at 70.6% conversion). In the presence of traceH_2O and NaOH, over the PtNi/ZrO_2 (0.4wt%Ni) catalyst the selectivity to hydrocinnamaldehydereaches 90.6% and the conversion of cinnamaldehyde is 90.5%. |
