| 摘 要： | 本文用二苯并-18-冠-6高聚物作因相化载体,通过化学健合,合成了担载的四核钴羰基簇催化剂Crown-Co_4。,并对该催化剂进行了元素分析、红外光谱及X射线光电子能谱(XPS)等方面的测试分析;还考察了不同温度、不同极性溶剂及不同类型烯烃对醛化活性的影响。实验证明,该催化剂对直链端位烯烃的醛化活性高于均相的苯基-四核钴羰基簇催化利Ph-Co_4。。二苯并-18-冠-6高聚物载体能明显改善催化性能。

| Abstract: | Tetranuclear-cobalt carbonyl cluster,supported on dibenzo-18-crown-6polymer (Crown-Co_4) was synthesized,and characterized by infrared spectroscopy,elemental analysis and XPS.The effect of temperature,solvents and alkenes upon thecatalytic hydroformylation activity was investigated.The experimental results showedthat the activity of Crown-Co_4 catalyst for terminal olefins is higher than that of thehomogeneous phenyl-tetranuclear-cobalt carbonyl cluster catalyst(Ph-Co_4).The improve-ment of catalytic activity by DB-18-C-6 polymer was evident. |
