RT info:eu-repo/semantics/article T1 Thermodynamics of ketone + amine mixtures. I. Volumetric and speed of sound data at (293.15, 298.15, and 303.15) K for 2-propanone + aniline, + N- methylaniline, or + pyridine systems A1 Alonso de Miguel, Iván A1 Alonso Gómez, Víctor A1 Mozo, Ismael A1 García de la Fuente, Isaías Laudelino A1 González López, Juan Antonio Mariano A1 Cobos Hernández, José Carlos AB Densities, , and speeds of sound, u, of 2-propanone + 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 analyser Anton Paar model DSA-5000. 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.
