Abstract

Densities (rho) have been measured for N,N-dimethylformamide (1), 2-methoxyethanol (2), and for nine binary mixtures covering the whole miscibility field (0 less-than-or-equal-to X1 less-than-or-equal-to 1) in the temperature range - 10- + 80-degrees-C. The experimental data were used to test some empirical equations of the type rho = rho(t), rho = rho(X1) and rho = rho(t, X1). Furthermore, the excess volumes (V(E)) for these binaries have been examined and discussed at all the investigated temperatures in terms of the influence of interactions between unlike molecules. The V(E) vs. X1 plots suggest the presence of some stable adducts, having N,N-dimethylformamide: 2-methoxyethanol stoichiometric ratios of 1 : 2 and 1 : 1 depending on the temperature.
