中文摘要 | the activity and selectivity of the transition metal complexes formed from ru, rh, pd and ni with triphenylphosphine (tpp) have been investigated for hydrogenation of citral in supercritical carbon dioxide (scco(2)). high activities are obtained with ru/tpp and pd/tpp catalysts, and the overall activity is in the order of pd approximate to ru > rh > ni. the ru/tpp complex is highly selective to the formation of unsaturated alcohols of geraniol and nerol. in contrast, the pd/tpp catalyst is more selective to partially saturated aldehydes of citronellal. furthermore, the influence of several parameters such as co2 and h-2 pressures, n-2 pressure and reaction time has been discussed. co2 pressure has a significant impact on the product distribution, and the selectivity for geraniol and nerol can be enhanced from 27% to 75% with increasing co2 pressure from 6 to 16 mpa, while the selectivity for citronellol decreases from 70% to 20%. striking changes in the conversion and product distribution in scco(2) could be interpreted with variations in the phase behavior and the molecular interaction between co2 and the substrate in the gas phase and in the liquid phase. |
