Abstract
Relative permittivities (E 12) have been measured for 2-metoxyethanol (ME)-tetrahydrofuran (THF) binary liquid mixtures over the whole compositions range at various temperatures ranging from 291.15 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-E 12]. From all these data, the temperature coefficients of relative permittivities (α12) and the excess extrathermodynamic parameters εE were calculated. The 1H-NMR spectra of liquid binary mixtures of ME and THF, 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, δδ(ME-THF). These structural parameters as a function concentration suggest the formation of stable 3ME.THF types intermolecular complexes.
