PREPARATION OF NONIONIC WATER-SOLUBLE PHOSPHINES AND THEIR RHODIUM COMPLEXES FOR CATALYTC HYDROFORMYLATION OF OLEFIN

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.
