| 摘 要： | 我们以自己合成的十个稀土(La、Cr、Pr、Nd、Sm、Gd、Ho、Er、Yb)的戊二酮配合物为主体,与三苯基膦(pph_3)、倍半氯乙基铝(Al_2Cl_3Et_3)组成三组份复合催化体系,对此催化剂催化丙烯齐聚反应进行了研究,得出随着稀土原子的原子序 X 数呈周期性变化,其催化活性发生规律性的变化,主产品六碳烯烃的分布类似。

| Abstract: | The Qligomerization of Propylene was studied using a triple catalyst system consising of rare earth 2,4-pentadionate,triphenylphosphine and ethylaluminum sesquichoride.It was known that the catalyst activity changed with the electronic structure of the rare earth element.And we also found that under the optimum reaction conditons,these triple cata- lyst systems were most active not only for the oligomerization of Propylene but also for the isomerization(doube bond and geometric)of the dimer products. |
