摘要
离子交换膜作为醇/水和其他有机水溶液的渗透汽化分离膜有很好的选择性。其中尤以磺化聚乙烯离子交换膜最为显著。用磺化聚乙烯离子膜分离恒沸组成的异丙醇/水和乙醇/水(85∶15wt%)混合物、近恒沸组成的二氧六环/水混合物。
The sulfonated polyethylene hollow fiber ion-exchange membranes with different ionexchange capacity (IEC) were prepared by heterogeneous photochemical chlorosulfonation reaction. The effects of temperature and IEC on the pervaporation of a near azeotropic isopropanol/water feed mixture were studied.
