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。
The experiments using photoelectron spectroscopy, infrared spectroscopy, nuclear magnetic resonance and solvent stripping and other methods confirmed that the titanium ether complex with 3TiCl 3 AlCl 3 catalyst solid-phase reaction. The surface of TiCl 4 · 2Et 2 O + 2AlCl 3 → TiCl 4 + 2AlCl 3 · Et 2 O treated by TiCl 2 complex can be approximated by three-layer model. Titanium ether complex with its electron donor and Lewis acid two components affect the performance of the catalyst. The electron donor component can still induce the migration. The solid-state reaction also brings about the change of coordination environment in the local area, resulting in new surface defects, all of which are beneficial to the bonding load of the reaction product (titanium tetrachloride). At last, some tentative ideas are put forward for the development of highly efficient supported catalysts.
