In this study, experimental data of density and speed of sound have been measured for binary liquid mixtures containing [n-butylammonium oleate (N(4)Ol) 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, , and deviation in isentropic compressibility, Delta kappa, 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 H-1-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. (AU)
