equilibrium data (LLE) for the mixtures of ionic liquid (IL) + alkane
+ aromatic {1-butylpyridinium nitrate, [BPy][NO3] (1) +
heptane, octane, or decane (2) + ethylbenzene (3)} and {[BPy][NO3] (1) + heptane, octane, or decane (2) + p-xylene (3)} at T = 298.15 K and P = 89 Kpa were measured. The degree of reliability of the experimental
LLE data was examined by using the Othmer-Tobias and Hand correlation.
For the six studied ternary mixtures, the separation factor and distribution
ratio of aromatic hydrocarbons derived from LLE data and were applied
to determine if [BPy][NO3] can be used as dearomatization
solvent. The separation of aromatic compounds with similar molecular
weight (ethylbenzene and p-xylene) from alkanes demonstrates
that p-xylene can be separated more easily from alkanes.
The triangular phase diagrams for all studied systems were sketched,
and the tie lines were compared with the NRTL model.
