摘要: Densities, ρ, and speeds of sound, u, 2-butanone + aniline, N-methylaniline, or pyridine systems have been measured at (293.15, 298.15, 303.15) K atmospheric pressure using a vibrating-tube densimeter sound analyzer (Anton Paar model DSA-5000). The ρ u values were used to calculate excess molar volumes, VE, the functions 298.15 for speed uE, thermal expansion coefficient, αPE, isentropic compressibility, κSE. VE κSE are both negative magnitudes increase in sequence: aniline < N-methylaniline pyridine. In contrast, uE is positive changes opposite way. Data suggest existence strong interactions between unlike molecules.
