Volumetric and Speed of Sound Data at (293.15, 298.15 and 303.15) K for Mixtures of 2-Heptanone with Aniline, N -Methylaniline or Pyridine [Elektronische Daten] [Iván Alonso, Ismael Mozo, Isaías De LaFuente, Juan González, José Cobos] Densities, ρ, and speeds of sound, u, of 2-heptanone + aniline + N-methylaniline or + pyridine systems have been measured at (293.15, 298.15 and 303.15)K and atmospheric pressure using a vibrating tube densimeter and sound analyzer. The ρ and u values were used to calculate excess molar volumes, V E, and the excess functions at 298.15K for the speed of sound, u E, the thermal expansion coefficient, $\alpha_{p}^{\mathrm{E}}$ , and for the isentropic compressibility, $\kappa_{\mathrm{S}}^{\mathrm{E}}$ . V E and $\kappa_{\mathrm{S}}^{\mathrm{E}}$ are both negative and increase in the sequence: aniline <N-methylaniline < pyridine. In contrast, u E is positive and changes in the opposite way. The data suggest the existence of interactions between unlike molecules, which are much weaker in the pyridine solution. Aromatic amine-alkanone interactions are stronger in mixtures with acetone. The linear dependence of Rao's constant with concentration reveals that there is no complex formation in the investigated systems.
