摘要：

The idea of two-phase (aqueous/organic) catalysis has attracted great attention in recent years due to the easy separation of catalyst from organic products by simple decantation and the environmental benefits. However, in the case of higher olefin hydroformylation, the unacceptable low reaction rate was observed due to its very low solubility in water. In fact many efforts have been devoted during the last years to find efficient means either to improve the mass transfer of the reactants or to maintain the active species at the interface, mainly by using a co-solvent, a cyclodextrin, a surfactant, an amphiphilic ligand, a carbohydrate modified phosphine or by supported aqueous phase catalysis and water-soluble polymer ligand.
