| Abstract: | Water-soluble ligands, tri4-methoxyl-3-(sodium sulfonato)phenyl]phosphine (4-MOTPPTS) and tri2-methoxyl-3-(sodium sulfonato)phenyl]phosphine (2-MOTPPTS) were synthesized and their application as ligand in Rh-catalyzed hydroformylation of higher olefin was investigated in aqueous biphasic catalytic system. The electron-donating methoxyl group of aromatic ring in phosphine ligand induced the decrease of the activity and selectivity for aldehyde of Rh catalyst than TPPTS used as ligand. The Rh catalyst with more crowded and basic 2-MOTPPTS showed lower activity than 4-MOTPPTS. |
