제목 Multi-functional zwitterionic compounds as new membrane materials for separating olefin/paraffin mixtures
초록 various types of multi-functional zwitterionic compounds containing both an ester and a sulfonate groups were prepared and their silver nitrate salts were tested as carriers for the facilitated olefin transport membranes in the separation of ethylene/ethane and propylene/propane mixtures. Ester group-containing multi-functional zwitterionic silver compounds exhibited much higher performances in comparison with methyl group-containing zwitterionic compounds. FT-IR study showed that ester-containing zwitterionic compounds interact with silver ions through both sulfonate and ester functional groups.
