Excess molar volumes, V E , isentropic compressibility, j s , isentropic compressibility deviations, Dj s , and changes of refractive index on mixing, Dn D , for the above systems, have been calculated from experimental data and fitted to Cibulka, Singh et al., and Nagata and Sakura equations, standard deviations from the regression lines are shown. Geometrical solution models, Tsao and Smith, Kholer, Jacob and Fitzner, Rastogi et al. were also applied to predict ternary properties from binary contributions.

Deviation of viscosity, excess molar volume, thermal expansivity coefficient, excess thermal expansivity coefficient and excess Gibbs energy of activation for viscous flow were
