本工作合成的高交换容量苯乙烯大孔强碱1型阴离子交换树脂80A,理化性能接近于Amberlite IRA900C的水平。80A的重量交换量为4.0～4.4meq/g(干树脂),比表面积为40～50m~2/g,平均孔径为90～100。80A的中间体,是苯乙烯—二乙烯苯共聚物(白球)及其氯甲基化产物(氯球)。白球交联度为6～10,以汽油、液体石腊为混合致孔剂。氯甲基化反应,采用无水三氯化铝为催化剂,反应温度35～40℃,反应时间约8小时,氯球的氯含量高达20～23％。
This work synthesis of high exchange capacity styrene macroporous strong base type 1 anion exchange resin 80A, physical and chemical properties close to the level of Amberlite IRA900C. 80A has an exchange weight of 4.0 to 4.4 meq / g (dry resin), an intermediate having a specific surface area of 40 to 50 m 2 / g and an average pore diameter of 90 to 100.80 A, and is a styrene-divinylbenzene copolymer White ball) and its chloromethylation product (chlorine ball). White cross-linked degree of 6 to 10, with gasoline, liquid paraffin as a mixed porogen. Chloromethylation reaction, using anhydrous aluminum chloride as a catalyst, the reaction temperature is 35 ~ 40 ℃, the reaction time is about 8 hours, chlorine content of chlorine ball as high as 20 to 23%.
