Density and absolute viscosity were measured for four binary mixtures composed by ethylene glycol diethyl ether and 1-alkanol (1-propanol to 1-hexanol). The measurements were carried out at 0.1 MPa and at four temperatures between 293.15 and 323.15 K. The density for the pure fluids and mixtures was correctly modeled with a perturbed chain-statistical associating fluid theory equation of state (PC-SAFT EoS). On the other hand, free volume theory combined with the equation of state was able to correctly model the absolute viscosity for all mixtures. The Redlich–Kister model was successfully applied in the correlation of derived properties as deviation in viscosity and excess volume. Also, the molecular interactions were studied from PC-SAFT EoS and the results of the excess volume.
