N2 - Liquid-liquid equilibrium data are critical for designing the extraction equipment or calculating the thermodynamic limit of a given separation. In this work, the LLE data were measured for the cyclohexane + (benzene, + toluene, + ethylbenzene, or + o-xylene) + 4-methyl-N-butyl pyridinium tetrafluoroborate ([bmpy]BF4) systems at 303.15 K under atmospheric pressure. The consistency of the measured LLE data was tested using the Othmer-Tobias correlation and the root-mean-square deviation (rmsd) in the mass fraction of [bmpy]BF4 in the lower phase and the average value of the absolute difference (AAD) between experimental mass fraction of cyclohexane in the upper phase and that calculated using the Othmer-Tobias correlation.
