采用物理浸渍法将室温离子液体1-丁基-3-甲基咪唑六氟磷酸盐负载到无机多孔材料人造沸石上,研究了分散溶剂的种类、离子液体加入量、振荡反应时间、振荡强度等条件对离子液体负载率的影响,并采用SEM、EDX和XRD的方法对离子液体负载型人造沸石进行表征。研究结果表明:采用浸渍振荡法负载离子液体时,以二氯甲烷为分散溶剂、离子液体与人造沸石质量比为1:3、振荡反应时间为12 h时离子液体在人造沸石上的负载率可达到最大值,接近70%;采用浸渍超声波负载离子液体时,超声波功率达到100%时负载反应时间大大减少至1 h,负载率为78.1%。
The ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate was loaded on the inorganic porous artificial zeolite by physical impregnation method. The effects of the type of dispersant, the amount of ionic liquid, the reaction time and the oscillation intensity were investigated. Conditions on the ionic liquid loading rate, and the ionic liquid loaded artificial zeolite was characterized by SEM, EDX and XRD. The results show that the loading rate of ionic liquid on artificial zeolite is better than that of artificial zeolite under the condition of 1: 3 ratio of ionic liquid to artificial zeolite and reaction time of 12 h with dichloromethane as solvent. Reaching the maximum value, close to 70%. When the ultrasonic liquid was immersed in the ionic liquid, the reaction time was greatly reduced to 1 h and the loading rate was 78.1% when the ultrasonic power reached 100%.
