The polydimethylsiloxane membranes containing 0, 10, 20 or 30 wt. % of ionic liquid (benzyl-3-butylimidazolium tetrafluoroborate) were used for separation of butan-1-ol from water. Pervaporation selectivity increased and the butan-1-ol flux through the membrane raised with the increased content of [BBIM][BF4] in the PDMS-[BBIM][BF4] membranes. The PDMS-[BBIM][BF4] membrane showed high stability as well as selectivity (the separation factor raised up to 37, if 30 weight % of ionic liquid was accommodated in PDMS) during all experiments.

Článek studuje separaci butan-1-olu z 5% vodného roztoku pervaporací. Selektivita pervaporace a celkový tok membránou roste s obsahem iontové kapaliny [BBIM][BF4] v membráně. PDMS-[BBIM][BF4] membrána vykázala vysokou selektivitu (separační faktor se zvýšil na 37, při obsahu 30% hm. iontové kapaliny [BBIM][BF4] v membráně) i vysokou stabilitu během všech experimentů.
