Correlation of liquid-liquid equilibria of non-ideal binary systems using the non-random, two-liquid model

Abstract

The non-random, two-liquid (NRTL) model with three different forms of temperature dependant parameters was used to correlate the liquid- -liquid 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.
