Popis: The non-random, two-liquid (NRTL) model with three different forms of temperature dependant parameters was used to correlate the liquid­liquid equilibrium data for systems of alcohols with alkanes, and alcohols with two ionic liquids: 1-butyl-2,3-dimethylimidazolium tetrafluoroborate ([bmmim][BF4]) and 1-butyl-3-ethylimidazolium tetrafluoroborate ([beim][BF4]). Different temperature dependences of the NRTL parameters were tested on thirteen literature experimental liquid-liquid equilibrium data for binary systems. NRTL model sa tri različita temperaturno zavisna parametra korišćen je za korelisanje ravnoteže tečno-tečno za binarne sisteme alkohola sa alkanima, kao i alkohola sa dve jonske tečnosti: 1-butyl-2,3-dimethylimidazolium tetrafluoroborate ([bmmim] [BF4]) i 1-butyl-3-ethylimidazolium tetrafluoroborate ([beim][BF4]). U radu su testirane tri različite forme temperaturne zavisnosti parametara NRTL modela. Ravnoteža tečnost-tečnost je modelovana na trinaest binarnih sistema. Kod svih sistema su dobijeni veoma zadovoljavajući rezultati sa srednjim greškama oko 3 %, korišćenjem sve tri forme temperaturne zavisnosti.
