| 摘 要： | 以乙二胺化交联聚苯乙烯树脂(PS-Acyl-EDA)和2-丙烯酰胺基-2-甲基丙烷磺酸(AMPS)为原料，通过Michael反应合成脂肪磺酸基强酸型阳离子交换树脂。该磺酸基强酸型阳离子交换树脂与传统的磺酸树脂相比，具有较长的手臂链，易于和其他物质反应或进行离子交换，且避免了芳香族磺酸树脂的磺化逆反应。讨论了反应时间、反应温度、催化剂用量、试剂用量及投料比等因素对反应结果的影响。通过对反应条件的优化，可获得担载量为0~1.15mmol•g-1的磺酸基强酸型阳离子交换树脂，并对产物进行了表征。该方法可用于色谱预装柱填料的制备。

| Abstract: | A novel aliphatic sulfonie acid ion exchange resin was prepared from ethylenediamined polystyrene （PS-acyl-EDA）, 2-acrylamido-2-methylproanesulfonic acid （AMPS）by Michael reaction.This kind of resin has a longer chain than conventional sulphonic polystyrene resin, that is, the former is easier to react with other compound.The effect of the reaction time,reaction temperature,catalyst amount,reagent amount and the charge ration on reaction result were discussed.Under the optimum condition, the maximum loading of the sulfonie acid ion exchange resin could be up to 1.15 mmol·g-1 resin.The product was characterized with FT-IR.The filling material of chromatographic column could be prepared by this method. |
