摘要

In this study, the copolymers with different ratios of AA(acrylic acid)-MMA(methyl methacrylate)-BA (butyl acrylate) are synthesized to prepare pervaporation membrane for the separation of methanol/MTBE (methyl tert-butyl ether)/C-5 mixtures. Swelling experiment of these copolymers in pure methanol, MTBE, C-5, and methanol/ MTBE mixtures are carried out, respectively. The results show that there is a strong interaction between MTBE and copolymer with high content of BA. The pervaporation characteristics of the membranes prepared with different copolymer are measured in the separation of methanol/ MTBE mixture. The experimental results show that the pervaporation ability changes with swelling degree in the same direction. The copolymers are characterized by FTIR. (C) 2003 Wiley Periodicals, Inc.
