Thermophysical Properties of Alkanone + Aromatic Amine Mixtures at Varying Temperatures.

ABSTRACT: In the present investigation, an attempt has been made to evaluate internal pressure (Pi) , energy (ΔEvap) , and enthalpy of vaporization (ΔHvap) along with excess entropy (SE)  and excess isothermal compressibility (βTE) for binary solutions of alkanones (2-propanone, 2-butanone, and 2-heptanone) and aromatic amines (aniline, N-methylaniline, and pyridine) at 293.15, 298.15, and 303.15 K, respectively. The cohesive energy density (CED) and solubility parameter (δ) are studied to understand the strength of molecular interactions. The coefficient of thermal expansion (α) and isothermal compressibility (βT) have also been investigated using empirical equations and have been employed to understand the molecular interactions. All the evaluated properties have been used to understand the nature
