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.

Abstract: Thermoregulated ligand Ph2P(CH2CH2O)16CH3-stabilized rhodium nanoparticles were investigated as the catalyst in the hydroformylation 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.
