摘要：
Refractive index (n) and related properties such as molar refraction (R) have been investigated for DMF+ME and DMF+DME binary mixtures over the entire composition range, at 15 different temperatures in the range 0 less than or equal to t/degreesC less than or equal to 70. Some relationships have been applied to study the dependence of the measured and derived quantities by temperature and composition. Furthermore, the excess functions n(E), R-E and the excess Kirkwood correlation parameters Deltag have been examined, in order to identify the presence of solvent-cosolvent adducts in these binary mixtures. The results obtained have been interpreted on the basis of specific intermolecular interactions between different species.
