摘要
Two kinds of nonionic water-soluble phosphine complexes:tri(o-polyglycol ether phenyl) phosphine(Ⅰ) and tri(p-polyglycol ether phenyl)phosphine(Ⅱ) (n=3~12) were prepared. Their thodium complexes preparedin sitn were used in aqueous/organic solvent two-phase system for catalytichydroformylation of olefin. The results implied that the surfactant phosphineligands for the biphasic hydroformylation of olefin shows good catalytic activityand selectivity,At 100 C and 6.0 MPa total pressure (CO/H=1:1) theconversion of (?) dodecene and selectivity to aldehyde were higher than 85%.The effects of different conditions on the hydrofurmylation reaction wereexamined.
