以丙烯、 1-己烯氢甲酰化为目标反应 ,研究了载体表面酸碱性、比表面积及孔径等对负载型水溶性铑膦配合物结构和催化性能的影响 .31 P(1 H) - NMR结果显示 ,水溶性铑膦配合物 HRh(CO) (TPPTS) 3负载到未经处理的 Si O2 表面后 ,配合物主要以 { Rh(CO) (TPPTS) 2 }物种形式存在 .负载型催化剂的活性和选择性与载体表面的酸碱性、比表面积、孔径密切相关 .载体孔径应足够大 ,以利于活性物种的负载及反应物 /产物的进出 The effects of surface acid-base, specific surface area and pore size on the structure and catalytic performance of supported water-soluble rhodium-phosphine complexes were investigated by hydroformylation of propylene and 1-hexene.31 P (1H) - NMR results showed that the complex was mainly existed as {Rh (CO) (TPPTS) 2} after HRh (CO) (TPPTS) 3 was loaded onto the surface of untreated Si O2. Catalyst activity and selectivity and carrier surface acid-base, surface area, pore size is closely related to the carrier pore size should be large enough to facilitate the active species load and reactants / products out
