摘要

The main transport properties of liquid or liquid mixtures are viscosity, diffusion, transference and electrical conductance. Viscosities of various liquid mixtures have been studied and their analyses have also been done by the help of some parameters. For each solution, the excess thermodynamic properties (Y~E) have been investigated. These excess thermodynamic properties are excess molar volume (V~E), viscosity deviation (?η) and excess Gibbs free energy of activation of viscous flow (AG*~E). These parameters provide us the important information about interaction between molecules. For example, the negative value of V~E and positive value of ?_η shows the strong interaction between the solute and solvent molecules while positive value of V~E and negative value of ?η shows the weak interaction between solute and solvent molecules. Above parameters and their discussion have been made in our earlier paper. In the present research paper, the viscosity data have been correlated with the equations of Grunberg and Nissan, Hind et al., Tamura and Kurata Katti. The excess values have been correlated using Redlich-Kister polynomial equation to obtain their coefficients and standard deviations. It has been found that in all cases, the data obtained fitted with the values correlated by the corresponding models very well. The results are interpreted in terms of molecular interactions occurring in the solution.
