聚四氟乙烯修饰的固体酸催化剂上异丁烯迭代反应性能
陈桂芳 李胜利 聊城大学东昌学院,山东聊城252000
摘 要:研究了硅胶负载的硅钨酸(H4SiW122O40,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I-ISiW/SiO:上,不仅对Cf选择性的提高效果较好,在酸性树脂上也同样有效,C8=选择性提高约10%。[著者文摘]

Reaction properties in isobutene oligomerization over teflon-modified solid acid catalystsCHEN Guifang * , LI Shengli Dongchang School, Liaocheng University, Liaocheng 252000, Shandong, ChinaAbstract: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%.[著者文摘]
