ABSTRACT

Densities, viscosities, ultrasonic speeds (u) and refractive indices (n_D) of the binary blends of 1,4- dioxane (DO) with ethylenediamine (EDA), 1,2-dichloroethane (DCE) and monoethanolamine (MEA) were measured at T = (298.15 318.15) K under atmospheric pressure over the entire composition range. Various experimental data were utilized to estimate the excess molar volumes (VE_m), excess viscosities (hE), excess molar refractions (RE_m), excess isentropic compressibility (kE_S), excess intermolecular free length (LE_f ), etc., and analyzed in terms of molecular interactions and structural effects. Partial molar volumes and excess partial molar volumes at infinite dilution of the components were derived and discussed in terms of volume changes. Prigogine-Flory-Paterson theory and Peng-Robinson equation of state were used to predict VE_m and viscosity values of the blends. IR spectra of the blends were correlated to the molecular interactions therein the blends.
