Kinematic viscosities (v) of the ternary ethane-1,2-diol (1) + 2-methoxyethanol (2)+ water (3) solvent system have been measured for 36 ternary mixtures covering the whole miscibility range expressed by the condition 0 <X-1,X-2,X-3 < 1, at 19 temperatures in the range - 10 less than or equal to t (degrees C) less than or equal to 80. The measured values have been used to test some empirical equations of the type v = v(t) and v = v(X-i), in order to provide for useful interpolation procedures to obtain calculated values in correspondence to the experimental data gaps. From the experimental data, the excess kinematic viscosities (v(E)) have been calculated. Sign and magnitude of these quantities have been discussed in terms of type and nature of specific intermolecular interactions. Furthermore, derived quantities such as thermodynamic parameters of the viscous flow (Delta G*, Delta H* and Delta S*), have been analysed on the basis of the Eyring's model. All the investigated excess mixing properties indicate the probable absence of stable three-component adducts in this ternary solvent system. (C) 1999 Elsevier Science B.V. All rights reserved.
