摘　　要：基于温控配体Ph2P(CH2CH2O)16CH3稳定的Rh纳米催化剂在水/1-丁醇两相体系中具有温控相转移功能,将其用于高碳烯烃氢甲酰化反应中.在优化的反应条件下,1-辛烯转化率和醛收率分别达98%和96%,对其它高碳烯烃氢甲酰化反应也具有较高的催化性能.催化剂和产物通过简单的相分离即可分开,连续使用3次后,催化剂性能未见明显降低.Thermoregulated ligand Ph2P（CH2CH2O）16CH3-stabilized rhodium nanoparticles were investigated as the catalyst in the hydro-formylation of higher olefins by thermoregulated phase-transfer catalysis in an aqueous/1-butanol biphasic system. Under optimized reaction conditions, the conversion of 1-octene and yield of aldehyde were 98% and 96%, respectively. The catalyst can be easily separated from the product by phase separation and was used for three times without evident loss in activity.
