席夫碱型聚苯乙烯多胺树脂的合成及性能研究
|
摘要
以乙酰化聚苯乙烯树脂为母体,与二乙烯三胺缩合制备了席夫碱型聚苯乙烯多胺树脂,分别研究了溶剂、催化剂、物料比、反应温度和反应时间等对反应的影响,并对树脂进行了结构表征,初步探索了树脂对Cu~(2+)的吸附行为。结果表明,在偏三甲苯中,以对甲苯磺酸为催化剂,160℃下反应16h,所得多胺树脂的全交换容量为3.99mmol/g,对Cu~(2+)的吸附量为63.5mg/g。
Schiff base-type polystyrene polyamines(PASDA) resins were prepared by condensation of acetylated polystyrene(PAS) resins and diethylenetriamine,The influence of solvent,catalyst,molar ration of raw materials,reaction temperature and reaction time on properties of PASDA resins were studied and the optimum reaction conditions were as follows,solvent was 1,2,4-Trimethylbenzene,catalyst was Ts OH,reaction temperature was 160℃,and reaction time was 16 h.The structure parameters of resins were characterized and measured.The adsorption of Cu~(2+) on PASDA resins was preliminarily studied,and the results indicated that total exchange capacity of PASDA resin was 3.99mmol/g and the adsorption capacity toward Cu~(2+) was 63.5mg/g.
