The viscosities and densities of mixtures containing polyethylene glycol monomethyl ether and 1-propanol have been determined in all concentration ranges between 5 ° and 45 °C. Experimentally determined values of properties in the dilute zone of polyethylene glycol monomethyl ether, have allowed the prediction of the viscosities of solutions in all concentration ranges and these have been compared with experimental values. We have used the Nakagawa procedure to predict the viscosity of regular solutions; he points that the Jones Dole B coefficient for nonelectrolyte solutions includes two contributions. The results obtained were better than those obtained using other correlations, even though our solutions cannot be considered as regular solutions.
