| 摘 要： | 合成了一系列含有聚乙二醇链和季铵盐两种活性中心的高分子相转移催化剂，并考察了它们在正溴辛烷与固体碘化钠的亲核取代反应中的相转移催化性能。结果表明，催化反应对ｎ—Ｃ８Ｈ１７Ｂｒ浓度为表观一级。温度、溶剂和微量水等反应条件对催化反应有较大影响，从反应动力学、本征反应性和内扩散等方面讨论了实验结果。

| Abstract: | A series of polymer- supported polyethylene glycol phase transfer catalysts with multiple active centers were immobilized by quaterisation of PEG tertiary amine with Chloromethylated copolymer (St-DVB). The kinetic reaction of 1 -bromooctane and solid sodium iodide catalyzed by this catalyst was investigated.The results showed the catalytic activity of this catalyst with PEG and onium as active centers was increased. |
