Influence of Ionic Liquid Content on Properties of Dense Polymer Membranes

Original language description

Pervaporation was used for removal of butan-1-ol from its 5 wt.% of aqueous solution, at which the concentration of Clostridium acetobutylicum starts to decrease. The polydimethylsiloxane(PDMS) membrane containing 0, 10, 20 or 30 wt.% of benzyl-3-butylimidazolium tetrafluoroborate ([BBIM][BF4]) ionic liquid was used. Differential scanning calorimetry measurements showed that PDMS-[BBIM][BF4] membranes (though optically homogeneous) contained PDMS and [BBIM][BF4] phases. Pervaporation selectivity increased and total flux through membranes raised moderately with an increased content of [BBIM][BF4] in PDMS-[BBIM][BF4] membranes. Hence, immobilization of a proper ionic liquid in a membrane results in the creation of pervaporation membranes, effective in the removal of alcohol from fermentation broths

Vliv iontových kapalin na vlastnosti neporézních polymerních membrán

Czech description

Článek studuje separaci butan-1-olu z 5% vodného roztoku pervaporací. Polydimethylsiloxanová membrána (PDMS) obsahovala 0, 10, 20 or 30 % hm. iontové kapaliny benzyl-3-butylimidazolium tetrafluoroborátu ([BBIM][BF4]). Diferenční skenovací kalorimetrií (DSC) bylo zjištěno, že membrána PDMS-[BBIM][BF4], ač opticky homogenní, obsahuje dislokované fáze PDMS a [BBIM][BF4]. Selektivita pervaporace a celkový tok membránou roste s obsahem iontové kapaliny [BBIM][BF4] v membráně. Zakotvením iontové kapaliny v membráně jsme schopni efektivně odstraňovat butan-1-ol z fermentačního brothu
