Application of Ionic Liquids and Sulfonated Poly(ether ether)ketone for the Facilitated Olefin Transport

다국어 초록 (Multilingual Abstract)

This research has been peformed to develop the olefin carriers of metal salts-polymer complex, polymer electrolytes, to investigate the coordinative interaction of olefin with silver ions in polymer electrolytes and apply zwitterionic silver complex to the facilitated transport membrane.
A remarkable separation performance of isoprene/n-pentane mixtures was observed through facilitated isoprene transport membranes prepared from silver complexes and zwitterionic salts. The performance of zwitterionic-silver complex membranes was tested for the separation of isoprene from n-pentane. The membranes were prepared by casting an aqueous solution containing zwitterionic and silver complex onto a polyester microporous membrane (47 mm, 0.1 ㎛, Whatman) using a doctor blade. Herein, we obtained marvelous phenomenon in the porous membrane.
The facilitated membranes based on sulfonated poly(ether ether)ketone (sPEEK) could be used to do the selective diene separation from the isoprene/pentane mixtures. The sPEEK membranes exchanged silver ions showed excellent separation factors for isoprene/pentane mixtures. The sPEEK-AgNO_(3) membrane was prepared and tested for the separation of isoprene/pentane. The membranes showed good selectivity of isoprene over n-pentane and long-term stability.
