在氯甲基化的苯乙烯-二乙烯苯聚合物的基体上,经后交联反应并分别用阿特拉津、氨基磺酸、偏苯三甲酸酐和浓硫酸物质加以修饰,以期得到既具有高比表面积又具有适量交换基团的吸附树脂。研究了邻氨基苯甲酸甲酯在5种吸附树脂上的静态吸附及动态吸附行为,并研究了FJ-1树脂的脱附行为。结果表明,化学修饰的吸附树脂对邻氨基苯甲酸甲酯的较优吸附温度为303K,具有丰富羧基基团修饰和合适孔径的吸附树脂对邻氨基苯甲酸甲酯有更好的吸附效果。FJ-1吸附树脂对邻氨基苯甲酸甲酯的动态吸附效果最好,该树脂吸附邻氨基苯甲酸甲酯后,易于脱附。用甲醇作为脱附剂,在温度333K,脱附流速0.5BV/h条件下,脱附率为75%。
In the chloromethylated styrene-divinylbenzene polymer matrix, after crosslinking reaction and were modified with atrazine, sulfamic acid, trimellitic anhydride and concentrated sulfuric acid substances were modified in order to obtain both have High specific surface area with the right exchange groups adsorption resin. The static adsorption and dynamic adsorption behavior of methyl anthranilate on five kinds of adsorbents were studied. The desorption behavior of FJ-1 resin was also studied. The results showed that the optimal adsorption temperature of methyl anthranilate on the chemically modified resin was 303K, and the adsorption resin with rich carboxyl groups and suitable pore size had better adsorption effect on the anthranilic acid methyl ester. FJ-1 adsorption resin on the dynamic adsorption of methyl anthranilate the best, the resin adsorption of methyl anthranilate, easy to desorption. Methanol was used as desorbent and the desorption rate was 75% at a temperature of 333 K and a desorption flow rate of 0.5 BV / h.
