- Abstract
- Both 1-benzyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [BzMeIM][NTf2], and 1-benzylpyridinium bis(trifluoromethylsulfonyl)imide, [BzPY][NTf2], were used to separate toluene from heptane through liquidliquid equilibria (LLE). The LLE of two ternary systems of toluene, n-heptane, and [BzMeIM][NTf2] and [BzPY][NTf2], were experimentally determined at temperature of 293.2 K and 0.1MPa. The LLE experiments were also performed at 303.2 and 313.2 K to investigate the effect of temperature on toluene recovery. The distribution ratio of toluene and the selectivity in these two ternary systems were calculated and compared with different ternary mixtures. The LLE measured data were well correlated with nonrandom two-liquid (NRTL).
