英文摘要	本实验应用光电子能谱、红外光谱、核磁共振及溶剂剥离等方法证实了钛醚络合物可与3TiCl_3·AlCl_3催化剂发生固相反应。 TiCl_4·2Et_2O+2AlCl_3→TiCl_4+2AlCl_3·Et_2O 经钛醚络合物处理后的催化剂表面可用三层结构模型近似。钛醚络合物以其给电子体和Lewis酸两种组份影响着催化剂的性能。给电子体组份仍可产生诱导迁移作用,伴随固相反应还出现局域配位环境的变化,产生新的表面缺陷,这些皆有益于反应产物(四氯化钛)的键合负载。最后对高效载体型催化剂的研制也提出了一些设想。; It has been verified by XPS, IR, NMR and solvent Washing that TiCl2 center dot 2Et(2)O Complex is able to react with 3TiCl(3)center dot AICl(3) Catalyst in solind phase as shown in table (1-1), table (3-2) and Fig. (2-1) - (2-4). The solid-solid reaction is as follows TiCl4 center dot 2Et(2)O + 2AlCl(3)-> 2AICl(3)center dot Et2O + TiCl4 After treatment with TiCl4 center dot 2Et(2)O complex the surface of the catalyst could be described approximately by a three layer model. [GRAPHICS] . Properties of the catalyst are effected by the donor and acceptor components from which the titanium ether complex is formed. The donor component still possesses induced migration effect. Accompanying the solid-solid reaction, there also exists some change in the Local Ligand environment of the ion in the catalyst. New surface vacancies also have appeared. All these are favourable to the supporting of the product (TiCl4) on the 3TiCl(3)center dot AICl(3) catalyst.; SCI(E); 0; 01; 57-65; 1
