چکیده انگلیسی
Density (Ï), speed of sound (u) and viscosity (η) have been measured for the binary mixtures of 3-chloroaniline with 1-alkanols (1-hexanol, 1-heptanol, 1-octanol, 1-decanol) over the entire composition range at (303.15, 308.15, 313.15, and 318.15) K. By using this data, the excess volume (VE), excess isentropic compressibility (κsE), deviation in viscosity (Îη) and excess Gibbs free energy of activation of viscous flow (GâE) have been calculated and were fitted to Redlich-Kister polynomial equation. The excess molar volumes, excess isentropic compressibility, deviation in viscosity and excess Gibbs energy of activation of viscous flow have been analyzed in terms of declustering and breaking of H-bonds in alkanols and alkyl chain of the 1-alkanols between unlike molecules. Moreover, the theoretical ultrasonic speeds are computed based on the scaled particle theory and compared with the experimentally measured values.
