2-Metoxyethanol-acetonitrile binary mixtures and their physicochemical properties

Densities (d(12)) and relative permittivities (epsilon (12)) have been measured for 2-metoxyethanol (ME) and acetonitrile (ACN) binary liquid mixtures over their whole compositions ranges at various temperatures ranging from 288.15 K to 308.15 K. The experimental data were used to test some empirical equations of the type: y(12)=y(12)(t) and y(12) =y(12)(X-1) (where: y(12)-d(12) or epsilon (12)). From all these data, the excess molar volumes (V-m(E)), temperature coefficients of relative permittivities (alpha (12)) and the excess extrathermodynamic parameters epsilon (E) were calculated. The H-1-NMR spectra of liquid binary mixtures of ME and ACN, were recorded at 298 K over almost the whole range of the mixed solvent compositions. From these data the values of the values of the spectral structural parameters were found, Delta delta (ME-ACN). The values of these structural parameters are discussed in terms of interactions of 2-metoxyethanol with acetonitrile.
