摘要
本文以己二酸对聚酰胺羧酸进行改性,制得改性聚酰亚胺膜,用于甲醇/甲基叔丁基醚的渗透汽化分离。研究了制膜液浓度、己二酸含量、原料液组成及温度等条件对膜分离性能的影响,并分析了膜的结构与特征基团的光谱图。
Adipic acid being used as a modifier, the modified polyimide membrane for pervaporation separation of MeOH/MTBE system was prepared. The effects of conditions, such as concentration of membrane-making solution, content of modifier, constituent and tempeature of mixture on membranes separation performance were studied. And the structures of membranes and the spectral graphs of characterized groups were also analyzed.
