由于AB-8树脂大量用于药物中间体的提取,树脂本身的一些残留物质是使用者非常关心的问题。AB-8树脂是一种具有孔穴结构的交联共聚体,它的制造原料包括单体、交联剂、添加剂(致孔剂、分散剂)。单体为苯乙烯,交联剂为二乙烯苯,致孔剂为烃类,分散剂为明胶。
AB-8型大孔吸附树脂是苯乙,烯型弱极性共聚体(交联剂为二乙烯苯,单体为丙烯酸甲酯,致孔剂为甲苯等)适宜水溶性具有弱极性物质的提取、分离、纯化,例如:甜苷、生物碱等。
问题处理
1、树脂被微生物污染后,可重新进行预处理或用小于0.5%次氯酸钠溶液浸泡,并用水洗净。
2、失水变干时,可用乙醇浸泡并水洗。
3、树脂遭铁污染时,可用4~10%盐酸溶液浸泡处理。
4、树脂受到有机物污染时,可用1%NaOH、10%NaCl盐碱混合溶液浸泡处理。
