Densities and viscosities of ten binary and ten ternary regular solution systems at 308.15 and 313.15Â K

► Knowledge of viscosity is valuable in industrial and engineering applications. ► The experimental data reported are a valuable addition to the literature. ► Testing viscosity models could lead to the development of new models. ► The generalized McAllister three-body interaction model performed the best. ► Predictive models gave much better results than the correlative models.
