【摘要】 在加氢汽油介质中Ni(naph)2Al(iBu)3(BF3·OEt2+nC8H17OH)体系为胶体催化剂的基础上,从电导率,UVVis光谱对催化剂各组分之间的相互作用作进一步的分析。得出催化剂组分以离子对的形式参与反应;Ni°在(Ni)(Al)陈化液中以团簇粒子形式存在,因吸附Ni+naph而稳定,因加入(B)而失去稳定性,聚结为胶粒,活性中心位于胶粒表面的观点;以及(Bd)预混不影响活性中心形成的观点得到进一步验证。从而加深了对活性中心结构的认识。

【Abstract】 The reaction mechanism of catalyst components was further analysed by electric conductivity and UV Vis spectrum.Further verified were the following conclusions: catalyst components reacted with each other in the form of ionic pair;there existed Ni(O) atom cluster(Ni 0) m in aged solution of <Ni> <Al>;the cluster were very stable because of adsorption of Ni +naph, and would become bigger as colloidal particles while <B〉 was added;active center was located on the surface of colloidal particles;and butadiene didn’t take part in the formation of active center.
