Abstract
Densities (rho) of the ternary mixtures 2-methoxyethanol + 1,2-dimethoxyeth ane + water have been measured at 19 temperatures in the range -263.15 less than or equal toT/K less than or equal to 353.15. The experimental data we re processed by empirical relations accounting for the dependence of rho on temperature and ternary composition expressed as mole fraction of the comp onents (0 less than or equal to x(i) less than or equal to 1). All checked equations seem to be suitable for correlation purposes, in order to obtain interpolated values in correspondence to experimental data gaps. Furthermor e, the excess molar volume (V-E) has been investigated to make evident the possibility of forming stable solvent-cosolvent adducts. The excess propert y has been interpreted on the basis of specific intermolecular interactions between the components.
