摘要
制备了膦配体修饰的Rh/SiO2多相催化剂(L-Rh/SiO2),该催化剂在内烯烃氢甲酰化制备正构醛反应中表现出了高活性和高区域选择性,而且在高压釜反应器中可以通过简单的过滤与产物分离.通过使用不同的单齿和螯合双齿膦配体考察了配体的电子及空间效应对L-Rh/SiO2催化剂催化性能的影响。
A phosphorus ligand-modified Rh/SiO2 catalyst (L-Rh/SiO2) has been developed for hydroformylation of internal olefins to linear aldehydes. This catalyst has high activity and regioseleetivity and can be separated easily by filtration after reaction in an autoclave. Moreover, the electronic and steric effects of phosphorus ligands on the catalytic performance of the L-Rh/SiO2 catalyst have been investigated by using various monodentate and chelating diphosphorus ligands.
