Description	Byl úspěšně testován systém iontové rozpouštědlo – polymer u vakuové pervaporace. Ultrafiltrační membrána byla impregnována 50 wt% iontovou kapalinou (1-ethenyl-3-ethyl-imidazolium hexafluoro-phosphate) a 50 wt% polydimethylsiloxanem. Tato velmi stabilní membrána byla testována na ternární směsi butan-1-ol-aceton-voda u vakuové pervaporace. Ve srovnání s polydimethylsiloxanovou membránou průměrný stupeň obohacení butan-1-olu v obou případech vzrostl. Toto zvýšení selektivity ukazuje na dobrý potenciál pro zlepšení pervaporačního separačního procesu. (cs) The use of ionic liquid–polymer in supported ultrafiltration membrane in vacuum pervaporation has been verified. The ultrafiltration membranes were impregnated by two ionic liquids (1-ethenyl-3-ethyl-imidazolium hexafluorophosphate and tetrapropylammonium tetracyano-borate) and polydimethylsiloxane. These new and very stable supported ionic liquid–polymer membranes were used for separation of ternary mixtures butan- 1-ol–acetone–water by vacuum pervaporation. In comparison with polydimethylsiloxane membranes, the average enrichment factor of butan-1-ol increased in both cases. This higher selectivity shows a good potential for improving pervaporation separation process.
