摘要: Ultrasonic velocity (U), density (ρ) and viscosity (η) for the ternary liquid mixtures of water + propylene glycol tetrahydrofuran, dimethylformamide, dimethylsulphoxide 1,4-dioxane have been measured as a function composition at 303, 308 313 K. The experimental data used to calculate some excess thermodynamical parameters such (η E), free volume ( ), Gibb's energy (ΔG E) interaction parameter (d). results are discussed interpreted in terms structural specific predominated by hydrogen bonding.
