| 摘 要： | 已知在加氢汽油介质中Ｎｉ（ｎａｐｈ）２－Ａｌ（ｉ－Ｂｕ）３－（ＢＦ３·ＯＥｔ２＋ｎ－Ｃ８Ｈ１７ＯＨ）体系为胶体催化剂。本工作应用ＦＴ－ＩＲ谱结合Ｔｙｎｄａｌ效应、电导率、ＵＶ－Ｖｉｓ、ＥＳＲ谱对催化剂各组分的相互作用进行研究。得出Ｎｉ（ｎａｐｈ）２被Ａｌ（ｉ－Ｂｕ）３还原的主要产物是Ｎｉ０；被Ａｌ（ｉ－Ｂｕ）２ＯｉＢｕ还原的主要产物是Ｎｉｎａｐｈ。Ｎｉ０聚结成胶粒（Ｎｉ０）ｎ，胶粒表面的Ｎｉ０或吸附的Ｎｉ＋是活性中心组分，与（ｉ－Ｂｕ）２ＡｌＢＦ４形成配合物，给出了活性中心模型。丁二烯具有稳定胶粒的作用。

| Abstract: | By IR spectrum, Tyndall effect, electric conductivity, UV Vis and ESR spectra were studied the reaction mechanism of catalyst components. The main reduced product of Ni(naoh) 2 by Al(i Bu) 3 was Ni 0; the main reduced product by (i Bui) 2AlOiBu was Ninaph. Ni 0 aggregated as colloidal particles (Ni 0) n,Ni 0 and Ni located on the surface of colloidal particles were active center parts. They coordinated with (i Bu) 2AlBF 4. |
