ABSTRACT

The density, qijk and speed of sound, uijk of ternary {1-ethyl-3-methylimidazolium tetrafluoroborate (i) + pyrrolidin-2-one} or {1-methyl pyrrolidin-2-one (j) + cyclopentanone or cyclohexanone (k)} mixtures have been measured at temperatures (293.15, 298.15, 303.15, 308.15) K. The excess molar volume, VE ijk and excess isentropic compressibility, jES ijk (obtained by employing density and speed of sound data) have been fitted to Redlich Kister equation to determine ternary adjustable parameters along with their standard deviations. The VE ijk and jES ijk results have been tested in terms of Graph and Prigogine Flory Patterson (PFP) theories. The results indicate that VE ijk and jES ijk values calculated by Graph theory are comparable to the experimental values.
