用不同的方法制备了几种分离有机物的膜 ,如CA/PAN、PVA/PAN的复合膜 ,以及含金属离子载体的PVA膜 ,这些膜是复合膜或非对称膜 .测量了膜材料 (CA和PVA -Men + )的吸附特性并评价了其性能 .结果表明 ,CA和CTA膜以及几种复合膜适于分离MTBE/MeOH ,修正的溶解 -扩散模型可成功地估算MTBE/MeOH透过CA膜的渗透汽化分离性能 .从初步吸附试验看 ,含金属离子载体的PVA膜对分离苯 /环乙烷体系可能是一好的候选膜 . Several organic membrane separation methods, such as composite membrane of CA / PAN, PVA / PAN and PVA membrane containing metal ion carrier, were prepared by different methods, which were composite membrane or asymmetric membrane. And PVA -Men +). The results show that the modified C / D model can be successfully used to estimate the MTBE / MeOH permeation through CA and CTA membranes as well as several composite membranes for the separation of MTBE / MeOH. Pervaporation and Separation Performance of Membrane From the preliminary adsorption test, the PVA membrane containing metal ion carrier may be a good candidate membrane for the separation of benzene / cyclohexane system.
