Properties as density and dynamic viscosity were measured for four binary mixtures composed for ethylene glycol dimethyl ether + 2-alkanol (2-propanol, 2-butanol, 2-pentanol, and 2-hexanol). The measurements were carried out in the entire mole fraction range of the liquid phase, 0.1 MPa, and using four temperatures (293.15 K, 303.15 K, 313.15 K, and 323.15 K). The values of excess molar volume and deviation in dynamic viscosity were successfully correlated with the Redlich–Kister equation. Strong attractive forces are obtained for all binary mixtures. The perturbed chain-statistical associating fluid theory equation of state (PC-SAFT EoS) correctly modeled the density of binary mixtures. The free volume theory combined with the equation of state was able to modeling the viscosity of all the mixtures.
