Physical parameters such as densities, ρ, and refractive indices, n D , of pure gamma-valerolactone/2-alkoxyethanols and their binaries have been determined over the whole composition range at different temperatures (298.15, 303.15, 308.15, and 313.15 K) and pressure = 0.1 MPa. From the experimental results, excess properties such as excess molar volumes, V m E , deviations in refractive indices, Δ ϕ n D , and deviations in molar refractions, Δ ϕ R M , have been calculated. The predicted data were fitted to the Redlich−Kister-type polynomial equation to derive the binary interaction parameters and recognize standard deviations between experimental and calculated values of the liquid solutions. Furthermore, the partial molar volumes, V m,1 , V m,2 , and excess partial molar volumes, V m,1 E , V m,2 E , were also computed. The Prigogine−Flory−Patterson theory and Graph theory were employed to correlate experimental V m E values. The departure of real mixtures from ideal behavior was interpreted in terms of strength and nature of molecular interactions. Furthermore, Fourier-transform infrared spectroscopy studies of the investigated solution along with pure components were also reported to obtain a better insight into intermolecular interactions between unlike molecules. In our study, positive values of V m E and negative values of Δ ϕ n D were observed, which suggests weak dispersion forces between dissimilar molecules.

The intermolecular interactions of ferulic acid (FA), a promising cancer-preventive agent, in mixed aqueous alcohol solutions were investigated using volumetric, viscometric, and refractive index approaches. The density and viscosity of aqueous ethanol/1-propanol solutions of FA were measured at different temperatures (293.15, 298.15, 303.15, 308.15, and 313.15 K) under atmospheric pressure using a digital liquid densimeter and an automatic rolling-ball microviscometer, respectively. The refractive index of aqueous ethanol/1-propanol solutions of FA was measured at 298.15 K using a refractometer. The apparent molar volumes and limiting partial molar volumes were calculated from the measured solution density values. The viscosity B-coefficients and their variation with temperature, that is, dB/dT, were obtained from the viscosity data. The molar refractions of FA were calculated from the refractive index measurements. In addition, the variation of these thermodynamic parameters with solution composition and temperature was analyzed in the light of the solute–solvent intermolecular interactions. The structure making/breaking ability of FA in the studied aqueous alcohol systems was investigated by studying the dB/dT dependence.
