Abstract

The densities (rho) and excess molar volumes (V-E) for 1,2-dimethoxyethane + water binary mixtures were determined, when possible, at 19 different temperatures ranging from -10 up to +80 degrees C. The experimental measurements were used to test some empirical relations giving the dependence of the density on the temperature and binary composition: rho = rho(t), rho = rho(X-1), and rho = rho(t,X-1). Furthermore, the results of V-E 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.
