Abstract: Because of the lower activity of higher olefins in aqueous/organic biphasic catalysis system and the catalyst
separation of homogeneous catalysts ,ultrafine SiO2 nanoparticles were used as supports to immobilize amphiphilic phosphine -
complex to obtain supported catalysts for hydroformylation of 1 - hexene .Compared to the supported aqueous - phase catalysts
(SAPC) on ultrafine SiO support ,the ultrafine SiO2 - supported catalyst with amphiphilic phosphine - complex presented a
higher hydroformylation performance over a relatively wider range of support hydration .Since the water was distilled to organic
phase for more times recycled catalysts ,the drawbacks of ultrafine SiO supported water - soluble phosphine - Rh complexes
catalyst could be avoided by using supported liquid - phase catalyst prepared by using amphiphilic phosphine - Rh complexes ,
obtaining higher activity and selectivity of hydroformylation .

摘要: 针对均相催化反应后催化剂与产物分离困难和高碳烯烃在水-有机两相中反应速率较低的问题,采用水-有机两亲膦铑络合物负载到超细 SiO2载体上催化 1-己烯氢甲酰化反应,并与超细 SiO2制备负载水相催化剂比较,超细 SiO2负载型两亲铑膦络合物催化剂表现出较高的1-己烯氢甲酰化反应活性和选择性,且含水质量分数范围较宽,反应后产物与催化剂容易分离。两亲膦铑络合物超细SiO2负载液相催化剂可避免超细SiO2负载水相催化剂循环使用时水分被提取到有机相的缺点,同时获得较高的氢甲酰化反应活性和选择性。
