ABSTRACT

Density, speed of sound and viscosity values were measured for different binary mixture concentrations of ([Bmim][NTf2] + N-Methylaniline) and ([Bmim][Pf6] + N-Methylaniline) systems at temperatures from T = (298.15 to 323.15) K. VTF equation was used to fit the experimental viscosity values. The heat capacities of pure compounds were determined at temperatures from T = (298.15 to 323.15) K. With the experimental data, the excess values of - molar volume, isentropic compressibility, molar Gibbs free energy of activation and speed of sound were calculated. R-K equation was utilized to evaluate coefficients and standard deviations. Further, the molecular interactions in the binary mixture systems were analysed using the experimental FT-IR spectrum recorded at room temperature. The assumptions on the behaviour of molecular interactions from the analysis of excess parameters were supported by the spectroscopic studies.
