ABSTRACT

In this study, densities and viscosities of four binary systems {aniline/N,N-dimethylaniline + 1-butyl-3- methylimidazolium triflate ([bmim][OTf])} and {aniline/N,N-dimethylaniline + 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([bmim][NTf2])} were measured at atmospheric pressure and within the temperature range T = (288.15 to 333.15) K. Excessmolar volumes VE, viscosity deviations Dg and excessmolar Gibbs energies of activation of viscous flow centsG.E were calculated and the results were fitted to a Redlich-Kister polynomial equation. Also, enthalpic and entropic parts of the centsG.E function were determined, at the same composition, for three studied systems that exhibit completemiscibility, since {aniline + [bmim][OTf]} is a partially miscible system. Considering the calculated thermodynamic properties, molecular interactions in the investigated binary systems were analysed and are discussed.
