Topological Investigations of Mixtures Containing 1-Methylpyrrolidin-2-one, Benzene and Isomeric Chlorotoluenes: Excess Molar Volumes and Excess Isentropic Compressibilities

摘要: The density $$ \rho_{23} $$ and \rho_{123} speed of sound u_{23} u_{123} data benzene (2) + o- or m- p-chlorotoluene (3) binary ternary mixtures 1-methylpyrrolidin-2-one (1) + benzene have been measured over the entire composition range at 293.15, 298.15, 303.15 308.15 K. experimental densities speeds utilized to evaluate excess molar volumes, V_{23}^{{\text E}} V_{123}^{{\text , isentropic compressibilities, \kappa_{{{S,{\text 23}}}}^{{\text 123}}}}^{{\text studied mixtures. results indicate that for are positive negative full composition.
