| 2 | Ru/C催化剂上香豆素加氢制八氢香豆素(英文)显示文摘The production of octahydrocoumarin,which can serve as a replacement for toxic coumarin,was investigated using 5% Ru on active carbon(Ru/C) as the catalyst for the hydrogenation of coumarin. The hydrogenation was studied by optimizing the reaction conditions(pressure,solvent and coumarin concentration). The activity and selectivity of the Ru/C catalyst were compared for different solvents. The mechanism of coumarin hydrogenation was deduced. The formation of side products was explained. The optimal hydrogenation reaction conditions were: 130 °C,10 MPa,60 wt% coumarin in methanol,and 0.5 wt%(based on coumarin) of Ru/C catalyst. At the complete conversion of coumarin,the selectivity to the desired product was 90%. | Dana Bílková Petr Jansa Iva Paterová Libor erveny | 2015 | 催化学报2015，36，7： | 1 |
