摘要
以甲苯、苯甲醇和氯甲醚为基本原料,一锅法合成了极性超高交联吸附树脂HH-1;利用树脂HH-1上残留的大量未反应完全的氯甲基,加入苯胺对树脂HH-1进行了后交联反应,得到比表面积更大的超高交联吸附树脂HH-2。并对两种树脂进行了分析表征,分析结果表明,树脂HH-1和树脂HH-2的比表面积分别为67.85m2/g和555.22m2/g,平均孔径分别为1.882nm和1.105nm。以亲水性小分子水杨酸作为吸附对象,研究了两种树脂对水杨酸的吸附行为。结果表明,交联后树脂HH-2对水杨酸的吸附能力是交联前树脂HH-1的5倍。主要原因是二次交联后,树脂的比表面积得到了大幅度提高。
The hypercrosslinked resin HH-1 was prepared by Friedel-Crafts post-crosslinking reaction with toluene,chloromethyl methyl ether and benzyl alcohol. HH-2 was synthesized by modifying HH-1 with aniline. The physical properties of the absorbents showed that HH-2 has higher surface area （555.22m2/g）than that of HH-1（67.85m2/g）,while the pore radius of HH-2 （1.105nm ） is lower than that of HH-1（1.882nm）. According to the adsorption experiment in aqueous solution,the adsorption capacity of salicylic acid onto HH-2 was 5 times as much as that of HH-1. Higher surface area of resin HH-2 is the main reason.
