ABSTRACT

Densities and refractive indices have been measured at 293.15, 298.15, 303.15 and 308.15 K for the binary mixtures of N-methylmorpholine and ethanol over the entire composition range. These data have been used to compute the excess molar volumes, VE and excess refractive indices, nE. The results are used to study the nature of molecular interactions in these mixtures.
