摘要：

Thermodynamic interactions in 2-methoxyethanol (component 1)+1,2-dimethoxyethane (component 2) binary mixtures have been studied in terms of the excess molar volume from the densities, measured at 19 temperatures between -10 and 80-degrees-C, for nine binary mixtures covering the whole miscibility field expressed by the mole fraction 0 less-than-or-equal-to X1 less-than-or-equal-to 1. Excess molar volumes are discussed in terms of induced conformational changes in each component in the presence of the other. The present findings support a hypothesis about the formation of a solvent-cosolvent complex species which has a well defined 1:1 stoichiometric composition and is thermostable under the experimental conditions.
