| 摘 要： | 针对双氧水氧化环己烯合成环氧环己烷的反应体系,采用大孔树脂动态吸附分离反应液水相中的1,2-环己二醇。结果表明,在自行设计吸附柱的基础上,AB-8大孔树脂吸附分离反应液水相中1,2-环己二醇的较佳条件为:上样流速1.0 mL/min,床层高度4.0 cm,常温;通过固定床吸附数学模型得到的速率常数、相关系数、吸附量和动力学参数,能较好地描述AB-8大孔树脂固定床吸附1,2-环己二醇的吸附动力学。以乙酸乙酯为脱附剂进行脱附的较佳条件为:洗脱流速1.0 mL/min,常温;AB-8大孔树脂经5次循环使用后其吸附率和脱附率仍在80%以上。

| Abstract: | For the reaction system of cyclohexene oxidation product epoxy cyclohexane by hydrogen peroxide,the technology of macroporous resin was adopted for the adsorption and separation of 1,2-cyclohexanediol in reaction aqueous solutions.The results show that,on the basis of the self-made absorption column,the more optimum conditions for adsorption and separation of 1,2-cyclohexanediol in reaction aqueous solutions by AB-8 resin were:sample flow rate 1.0 mL/min,bed height 4.0 cm,and normal temperature.The rate con... |
