| Abstract: | Pt/Al2O3 was used as catalyst for selective hydrogenation of 2 - propyl - 2 - heptenal to produce 2 -propyl heptanal. The experiment was carried out in a fixed - bed reactor. The results showed that 93 % conversion of 2 - propyl - 2 - heptenal and 96 % selectivity to 2 - propyl heptanal were obtained respectively under the reaction conditions of pressure 1.0-1.5 MPa, temperature 413 K, molar ratio of H2 to 2 - propyl - 2 - heptenal 2.5:1, and LHSV 1.0-2.5 h-1. |
