چکیده انگلیسی
In this work, density and speed of sound of binary mixtures of {n-butylammonium butanoate ionic liquid (N4Bu) + alcohols (methanol, ethanol, 1-propanol, 1-butanol and 1-pentanol)} have been measured as a function of composition at T = (293.15-313.15) K and atmospheric pressure. The results were used to calculate the excess molar volume, VmE, and deviation in isentropic compressibility, ÎκS, and correlated to the Redlich-Kister polynomial equation. N4Bu was synthesized by the method of acid-base neutralization reaction using n-butylamine and butanoic acid, and characterized using 1H NMR, 13C NMR and FTIR spectroscopy techniques. For all systems studied, the values of excess molar volumes and deviations in isentropic compressibility were negative over the entire composition range. The results obtained were discussed in terms of structural effects and intermolecular interactions between like and unlike molecules.
