摘　　要：Four monodentate P-ligands and their mixtures（six groups of double-ligand systems,four groups of triple-ligand systems and one group of tetra-ligand system）were used with Rh（acac）（CO）2（acac=acetylacetonate）or Rh（acac）CO（PPh3）as the catalyst in the hydroformylation reaction of 1-butene.It was found that different Rh catalysts showed little difference in the catalysis performance.The general order of catalysis performance is doubleligand system 〉 single-ligand system〉triple-ligand system 〉 tetra-ligand system.Some synergistic effect in the double-ligand system was detected which needs a further investigation.Four monodentate P-ligands and their mixtures(six groups of double-ligand systems,four groups of triple-ligand systems and one group of tetra-ligand system)were used with Rh(acac)(CO)_2(acac=acetylacetonate)or Rh(acac)CO(PPh_3)as the catalyst in the hydroformylation reaction of 1-butene.It was found that different Rh catalysts showed little difference in the catalysis performance.The general order of catalysis performance is doubleligand system N single-ligand system N triple-ligand system N tetra-ligand system.Some synergistic effect in the double-ligand system was detected which needs a further investigation.
