摘要
合成了共聚苯乙烯 -二乙烯基苯担载四聚乙二醇苄基季铵盐及共聚苯乙烯 -二乙烯基苯担载四聚乙二醇接 2 - (+ ) -烷基 - 4 ,5 -二氢咪唑啉类季铵盐 ,探讨了它们在 n-溴辛烷与碘化钾反应中的相转移催化活性。
The synthesis of polystyrene.divinylbenzeneresins.supported methylene.tetrapoly.oxy. ethylene.[WT5,5”BX]N.benzyl.[WT5,5”BX]N, N.[WT5,5”BZ]dimethylammonium and methylene.tetrapolyoxyethylene.[WT5,5”BX]N.hydroxyethyl.2. undecyl.4,5.dihydroimidazolium chloride was reported. Their catalytic activity in the substitution reaction of n.octyl bromide with potassium iodide was also investigated.
