摘要
The aqueous biphasic hydroformylation of oleyl alcohol was achieved under thermo-regulated phase transfer catalysis (TRPTC) conditions with Rh(acac)(CO)2 Ph2P[p-C6H4 (OCH2CH2)25OH] (PETPP) complex catalyst formed in situ. The aldehyde yield reached 81.2% within 6 hrs under 140℃ and 5.0 MPa (CO/H2,1/1) and the separated catalysts dissolved in the aqueous phase could be reused for 3 times without evident changes in activity.
