    AnnotationIn this work, the selective removal of butanol from aqueous solution by pervaporation with a PIM-1 membrane was studied. The freshly cast and aged (370 days) PIM-1 membrane was used for pervaporation experiments at 50 °C. The aged PIM-1 membrane exhibited a dramatic decrease in permeability compared to the freshly cast membrane, from 14 to 2 mg/m/h, but simultaneously a tremendous increase of selectivity, from 24 to 47, for the separation process at 2 wt.% of butanol. The aging effect may be attributed to slow rearrangement of polymer chains, resulting in densification and reduction of accessible free volume. Pervaporation with the PIM-1 membrane was found to be effective only for low concentration of butanol in an aqueous feed, i.e. an increasing butanol concentration in the feed led to a decrease of the enrichment factor.
