摘要: Abstract Densities and viscosities of ternary mixtures 2-pyrrolidone + 1,2-propanediol + water corresponding binary 1,2-propanediol + water, 2-pyrrolidone + water 2-pyrrolidone + 1,2-propanediol have been measured over the whole composition range at 313.15 K. From obtained data, excess molar volumes ( V E ), deviations in viscosity (Δ η ) Gibbs free energy activation G ⁎ calculated. The , Δ results were correlated fitted by Redlich–Kister equation for Cibulka mixtures, as a function mole fraction. Several predictive empirical relations applied to predict from mixing data.
