| 摘 要： | 通过Ｔｙｎｄａｌ效应，超过滤实验和电镜观察证明，ＭｏＣｌ３（ＯＣ８Ｈ１７）２－（ｉ－Ｂｕ）２ＡＩＯ催化剂在加氢汽油溶剂中呈胶体分散，胶粒主要是由ＭｏＣｌ３（ＯＣ８ｈＨ１７）２聚集，同时与（ｉ－Ｂｕ）２ＡＩＯ反应，活性中心位于胶粒表面，所以钼体系为胶体催化剂，属多相催化，陈化对胶粒的形态影响不大，是比较稳定的胶体体系。

| Abstract: | The phase of molybdenum catalyst system was studied with hydrogated gasline as solvent and with MoCl 4 OC 8 H 17 (i Bu)AlO as catalyst. By means of Tyndall effect and electron microscope observation it was found that Molybdenum catalyst was colloid catalyst.To ascertain the location of active centers of catalyic polymerization an ultrafiltration experiment was performed by a pore filter.The active centers existed in the surface of the colloid particles,and so the overall catalyst polymerization was a heterogeneous catalytic reaction. |
