【摘要】 通过Ｔｙｎｄａｌ效应，超过滤实验和电镜观察证明，Ｆｅ（ｎａｐｈ）２┐Ａｌ（ｉ┐Ｂｕ）３┐ＣＨ２＝ＣＨＣＨ２Ｃｌ催化剂在加氢汽油溶剂中呈胶体分散系。Ｆｅ（ｎａｐｈ）２与Ａｌ（ｉ┐Ｂｕ）３的反应是形式胶粒的基本反应。催化剂颗粒是无定型的。催化剂各组分的配比影响颗粒的形态，其中以较佳配比所得的催化剂颗粒较小，分布比较均匀，而且催化活性高。由于是胶体催化剂，颗粒表面上的活性中心起催化作用，因此催化剂的利用率低。由于是不稳定胶体体系，陈化使颗粒聚集增大，降低了催化剂的活性。更多还原

【Abstract】 The phase state of iron catalyst system, Fe(naph) 2 Al(i Bu) 3 CH 2=CHCH 2Cl,was studied. By means of Tyndall effect and electron microscope, it was found that iron catalyst system with hydrogated gasoline as solvent was colloid catalyst. In order to determine wherethe active centers in this catalytic polymerrization reaction were, an ultrafiltration experiment was done by a pore filter. The activecenters existed in the surface of the colloid particles. So the wholecatalytic polymerization reaction was a heterogeneous catalytic reaction.更多还原
