一.總論 離子交換樹脂是帶極性功能團的高分子化合物,不溶於任何有機及無機溶劑。因為樹脂具備了極性的功能團,如强酸基,中等酸基,弱酸基,强碱基,弱碱基等,故在適當的條件下能够催化許多類型的有機反應,与普通的無機酸,碱一樣。最顯著的例子,如:水解、縮合、加成、酯化、去鹵化氫、去水、氨解、醇解及酯交換等反應。 I. General Ion exchange resin is a polar functional group of polymer compounds, insoluble in any organic and inorganic solvents. Because the resin has polar functional groups such as strong acid group, medium acid group, weak acid group, strong base, weak base and so on, it can catalyze many types of organic reactions under appropriate conditions, and ordinary inorganic acid, alkali same. The most notable examples are: hydrolysis, condensation, addition, esterification, dehydrohalogenation, dewatering, ammonolysis, alcoholysis and transesterification.
