英文摘要: The organic triphenyl-phosphine ligand was directly used to modify the Rh/SiO2 catalyst to prepare PPh3-Rh/SiO2 catalyst for hydroformylation of olefins. The results showed that its catalytic activity for hydroformylation of 1-hexene under the mild conditions of 1.0 MPa and 373 K was higher than that of Rh/SiO2 catalyst, and comparable to that of the corresponding homogeneous HRhCO(PPh3)(3) catalyst. The PPh3-Rh/SiO2 catalyst possessed the advantages of both heterogeneous catalysis and homogeneous catalysis, such as high activity, high selectivity and easy separation. By means of P-31 MAS NMR and XPS techniques for characterization of PPh3-Rh/SiO2 catalyst, it was found that the coordination bond between Rh metal and PPh3 with lone-pair electron was formed on the catalyst. The PPh3-Rh/SiO2 catalyst could be used in hydroformylation of olefins from C-2(=) to C-12(=).
