Density and Volumetric Behavior of 1,2-Dimethoxyethane + Water Binary Mixtures from −10 to 80 °C

The densities (ρ) and excess molar volumes (VE) for 1,2-dimethoxyethane + water binary mixtures were determined, when possible, at 19 different temperatures ranging from −10 up to +80 °C. The experimental measurements were used to test some empirical relations giving the dependence of the density on the temperature and binary composition: ρ = ρ(t), ρ = ρ(X1), and ρ = ρ(t,X1). Furthermore, the results of VE calculations are discussed in terms of the influence of interactions between the components, of the order and degree of packing in the mixtures, and of the free-volume differences.
