Abstract: Density, speed of sound, and refractive index for the binary systems (butanoic acid + propanoic acid, or
2-methyl-propanoic acid) were measured over the whole composition range and at
T
= (293.15,
298.15, 303.15, 308.15, and 313.15) K. The excess molar volumes, isentropic compressibilities, excess
isentropic compressibilities, molar refractions, and deviation in refractive indices were also calculated
by using the experimental densities, speed of sound, and refractive indices data, respectively. The
Redlich–Kister smoothing polynomial equation was used to fit the excess molar volume, excess isentro-
pic compressibility and deviation in refractive index data. The thermodynamic properties have been
discussed in terms of intermolecular interactions between the components of the mixtures.
