Abstract

The density (ρ), viscosity (η), and speed of sound (u) were measured for binary mixtures of 3‑methyl-1-butanol(isoamylalcohol) with 1,2-dichloroethane (DCE), 1,1,2-trichloroethane (TCE), and 1,1,2,2-tetrachloroethane (TECE) over the entire range of mole fractions and at temperature 298.15, 303.15, and 308.15 K. From these measurements, the values of excess molar volume (VE), deviation in viscosity (∆η), deviation in isentropic compressibility (∆ks), excess Gibbs free energy of activation of viscous flow (G*E) and Grunberg−Nissan interaction parameter (d ') have been calculated. The excess parameter deviations have been fitted to Redlich−Kister type polynomial equation using multiparametric nonlinear regression analysis to estimate the binary coefficients and standard deviations. The results were discussed in terms of molecular interactions and dipole-dipole interactions. The effects of temperature and chlorine atoms number of investigated chloroethanes were also studied for the binary mixtures.
