  Several physical properties were determined for the ionic liquid   3-methyl-N-butylpyridinium tricyanomethanide   ([3-mebupy]C(CN)3): liquid density, viscosity, surface   tension, thermal stability and heat capacity in the temperature   range from (283.2 to 363.2) K and at 0.1 MPa. The density and the   surface tension could well be correlated with linear equations   and the viscosity with a Vogel–Fulcher–Tamman equation. The IL is   stable up to a temperature of 420 K.


  Ternary data for the systems {benzene + n-hexane,   toluene + n-heptane, and p-xylene +   n-octane + [3-mebupy]C(CN)3} were determined   at T = (303.2 and 328.2) K and p = 0.1 MPa. All   experimental data were well correlated with the NRTL model. The   experimental and calculated aromatic/aliphatic selectivities are   in good agreement with each other.
