作者用五类聚合物配体与不同催化活性物种反应制备了负载催化剂,并考察了聚合物配体及聚合物载体上功能基(配体)对不同催化活性物种氢甲酰化催化性能的影响。实验结果表明:当聚合物配体相同时,Co_2Rh_2(CO)_(12)双金属簇催化活性物种优于RhCl_3·3H_2O及Rh_2(Co)_4Cl_2;聚(N——乙烯基吡咯烷酮)(PNVP)及马来酸酐与苯乙烯共聚物(PMAn)负载催化剂大多具有良好的氢甲酰化催化性能。
The authors used five kinds of polymer ligands with different catalytically active species to prepare supported catalysts and investigated the effect of functional groups (ligands) on the catalytic performance of hydroformylation of different catalytically active species on polymer ligands and polymer supports . The experimental results show that the active species of Co_2Rh_2 (CO) _ (12) bimetallic clusters is better than that of RhCl_3 · 3H_2O and Rh_2 (Co) _4Cl_2 when the polymer ligands are the same. The poly (N - vinylpyrrolidone) And maleic anhydride and styrene copolymer (PMAn) supported catalysts mostly have good hydroformylation catalytic properties.
