| 摘 要： | 醚类会被广泛用来改性Ziegler-Natta催化剂,如著名的Solvay型催化剂就是用异戊醚处理β-TiCl_3,国内研制的所谓络合Ⅰ型,或络合Ⅱ型催化剂则是用异戊醚或正丁醚作为络合剂。乙醚与四氯化钛的反应物对3TiCl_3·AlCl_3催化剂有显著的改进,给电子体醚可使铝在催化剂表面富集。因而研究醚与四氯化钛或三氯化钛络合物的结构是一个基本的问题。已知四氯化钛和醚可生成多种络合物,但其分子结构及晶体结构测定甚少,本

| Abstract: | The crystal and molecular structure of titanium ether complex has been determined by X-ray diffraction. TiCl_4 and Et_2O can form 1:2 complex, TiCl_4·2Et_2O, which is in cis-configuration. The crystal belongs to monoclinic space group C_(2h)~5P21/n with unit cell parameters: a=0.8877(4) nm, b=1.3115(8) nm, c=1.3437(8) nm, β=98.27(5)°, Z=4. The structure was refined to R_1=0.108、R_2=0.127 for 1002 reflections. It has been showed that the titanium ether complex which has been used to modify the catalyst (3TICl_3·AlCl_3) is TiCl_4·2Et_2O. The powder pattern and infrared spectra of the complex have also been got. Some bases for characterizing the catalyst have provided. |
