The and u values were used to calculate excess molar volumes, , and the excess functions at 298.15 K for the speed of sound, , the thermal expansion coefficient, , and for the isentropic compressibility, at 298.15 K. and are both negative magnitudes and increase in the same sequence: aniline < N-methylaniline < pyridine. The and curves are shifted towards higher mole fractions of 2-propanone. The data haven interpreted assuming strong acetone-amine interactions, and weak structural effects.
