Alonso de Miguel, Iván Alonso Gómez, Víctor Mozo, Ismael García de la Fuente, Isaías Laudelino González López, Juan Antonio Mariano Cobos Hernández, José Carlos 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. 2024-02-10 2024-02-10 2010 info:eu-repo/semantics/article Journal of Chemical & Engineering Data, 2010, 55 (7), 2505-2511 https://uvadoc.uva.es/handle/10324/66118 10.1021/je900874z eng info:eu-repo/semantics/restrictedAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 Internacional
