dc.description.abstract© 2022 Elsevier LtdVolumetric and acoustic properties were obtained by density (ρ) and speed of sound (u) experimental values for the binary liquid systems containing the protic ionic liquid (IL) sec-butylammonium methanoate (S4Met) + alcohols (ethanol, 1-propanol, 1-butanol and 1-pentanol) over the whole composition range at different temperatures (293.15–313.15) K and ambient pressure (p = 92.3 kPa). A neutralization reaction was carried out under controlled temperature to synthesize S4Met, which underwent spectroscopic analyses to guarantee its formation. All the excess properties, namely excess molar volume,VmE, excess partial molar volumes,V¯iE, and deviation in isentropic compressibility,ΔκS, presented negative values. Other volumetric properties such as partial molar volumes,V¯i, apparent molar volumes, Vϕi and infinite dilution volumes,V¯i∞, were determined. In addition to the thermodynamic approach, spectroscopy techniques essentially 1H NMR, 13C NMR, FTIR were useful in order to elucidate intermolecular interactions among the species in solutions. Lastly, the Peng-Robinson-Stryjek-Vera equation of state (PRSV EOS) was used to correlate the excess molar volumes.
