【Abstract】 Effect of the reaction pressure, the reaction temperature, the reaction time, and solvent, etc, on the hydrogenation of crotonaldehyde over Chitosan Pd were investigated. The best reaction conditions are as follows: the mol ratio of Pa: crotonaldehyde is 1:50,PH2=4.0 MPa, T=80℃.The conversion of crotonaldehyde and the selectivity to butanol were 100% and over 60% respectively.更多还原
