Thermodynamic and spectroscopic study of binary mixtures of n-butylammonium oleate ionic liquid + alcohol at T = 288.15-308.15 K. JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY, v. 131, p. 2925-2942, 2017.1588-2926https://repositorio.fei.edu.br/handle/FEI/1711© 2017, Akadémiai Kiadó, Budapest, Hungary.In this study, experimental data of density and speed of sound have been measured for binary liquid mixtures containing {n-butylammonium oleate (N4Ol) ionic liquid + 1-propanol, or + 1-butanol, or + 1-pentanol, or + 1-hexanol}, over the entire range of composition at temperatures from T = 288.15–308.15 K and atmospheric pressure. Excess molar volume, VmE, and deviation in isentropic compressibility, Δκ, were calculated using the experimental data and were fit to a Redlich–Kister type polynomial. In order to elucidate possible intermolecular interactions between the chemical species present in solution, FT-IR and 1H-NMR spectroscopic analyses were carried out. The results for all systems studied suggest that structural effects and dispersion-type interactions must predominate other possible effects.Acesso RestritoArtigo10.1007/s10973-017-6801-7AlcoholsIonic liquidSpectroscopyThermodynamic properties
