Selective Hydrogenation of Crotonaldehyde to Crotyl Alcohol on Ag-MnO2/Al2O3·5AlPO4 Catalysts

Abstract The activity and selectivity of Ag-MnO2/Al2O3·5AlPO4 catalysts for the hydrogenation of crotonaldehyde to crotyl alcohol have been investigated in liquid phase. When MnO2 was added to the catalyst, the activity and selectivity for the reaction were remarkably improved to give the conversion of 100 mol% and the selectivity of 69.5%.
