考察了编织芳基网络聚合物(KAPs)负载的Rh催化剂(Rh/KAPs)在高碳烯烃氢甲酰化反应中的催化性能。结果表明,三苯基膦-苯基底KAPs负载Rh催化剂(Rh/KAPs-1)具有优异的高碳烯烃氢甲酰化反应活性,产物醛收率显著高于Rh/SiO2催化剂。傅里叶变换红外光谱、热重、氮气吸附-脱附、X射线衍射、透射电子显微镜、13C核磁共振和31P核磁共振结果显示, Rh/KAPs-1催化剂具有优异的热稳定性及大的比表面积和多级孔道结构, Rh颗粒处于高度分散状态,并可在反应过程中形成均相催化活性物种。

Rh catalysts supported on knitting aryl network polymers (Rh/KAPs) were prepared for the hydro-formylation of higher olefins. Rh catalysts supported on triphenylphosphine-benzene-base poly-mers (Rh/KAPs-1) showed higher activity for the higher olefins than Rh/SiO2 catalysts. Fourier transform infrared spectroscopy, thermogravimetry, N2 adsorption-desorption, X-ray diffraction, transmission electron microscopy, 13C NMR, and 31P NMR showed that the Rh/KAPs-1 catalysts have high thermal stability, high surface area, hierarchical porosity, highly dispersed Rh nanoparti-cles, and in situ formed homogeneous active species during the reaction.
