| 摘 要： | 研究了硅胶负载的硅钨酸(H_4SiW_(12)O_(40),缩写HSiW)、Amberlyst-15和Amberlyst-35固体酸催化剂表面被聚四氟乙烯乳液修饰前后对异丁烯迭代反应性能的影响。结果表明,聚四氟乙烯涂敷在催化剂HSiW/SiO_2上,不仅对C_8~=选择性的提高效果较好,在酸性树脂上也同样有效,C_8~=选择性提高约10%。

| Abstract: | The effects of silica-supported 12-silicotungstic acids （H4SiW12O40, abbreviated as HSiW）, Amberlyst-15 and Amberlyst-35 modified by polytetrafluorethylene （teflon） on catalytic properties in isohutene oligomerization were investigated. The results indicated that teflon coated on HSiW/Si02 catalyst and acidic resins could enhance the selectivity to Cs-- about 10%. |
