Effect of Reaction Conditions on Catalytic Hydrogenation of Methyl Propionate

The Ru-Pt/AlOOH catalyst was prepared by impregnation and hydrothermal reduction and was used for catalytic hydrogenation of methyl propionate to n-propanol in water solvent.The effect of metal loading,solvent volume,reaction time,reaction temperature and hydrogen pressure were investigated in detail.The results indicated that the conversion of methyl propionate and the selectivity to n-propanol were obviously affected by these reaction conditions.Under the conditions of 180℃,hydrogen pressure 5.0MPa,reaction time 10 h,the conversion of methyl propionate attained to 89.1% and the selectivity to n-propanol was 97.8%.
