“…As the temperature increases from 298.15 to 318.15 K, the interstitial accommodation of the unlike molecule increases, which might be due to lattice expansion at elevated temperatures. This better accommodation causes more negative V m E values from 298.15 to 318.15 K. In an earlier report, monoethanolamine + n -propanol, the V m E values are negative (at 298.15 K or at x 1 ; 0.5, V m E ; −0.46), and negative values of V m E increased with an increase in temperature due to strong predominant dispersion attractive forces. The V m E values for the binary system containing 1-propanol with 1,3-diaminopropane are negative (at 298.15 K or at x 1 ; 0.5, V m E ; −1.21), and negative values of V m E increased with an increase in temperature.…”

The molecular interactions of ternary mixtures of 1-propanol + 1,3-diaminopropane + methyl acetate were studied by the insight into the physicochemical properties of given liquid mixtures. Density, viscosity, speed of sound, and refractive index data were measured for 1P, 1,3-DAP, MAc, and their ternary liquid mixtures at five different temperatures (T = 298.15–318.15 K) and at 0.1 MPa pressure. Based on the experimental data, excess molar volume, deviation in viscosity, deviation in ultrasonic speed, excess molar isentropic compressibility, excess free volume, excess intermolecular free length, excess available volume, and deviation in refractive index were calculated, and these evaluated properties were fitted to the Singh equation. The excess molar volume data were also fitted to the Nagata and Cibulka equations. Further, the Kohler model, Tsao–Smith model, Radojkovic model, Jacob–Fitzner model, and Rastogi model were used to calculate the excess molar volume values. Different correlations were applied for the estimation of the speed of sound and refractive index values.
