Refractive Indices and Surface Tensions of Binary Mixtures of 1,4-Dioxane + n-Alkanes at 298.15 K

Abstract

Refractive indices (n) for {1,4-dioxane + 1-hexanol, 1-heptanol, 1-octanol, 1-nonanol, or 1-decanol} and surface tensions (σ) for {1,4-dioxane + 1-hexanol, 1-heptanol, 1-octanol, or 1-decanol} at the temperature 298.15 K and normal atmospheric pressure have been determined as a function of mole fractions. The experimental data have been used to calculate refractive index and surface tension deviations (Δn, Δσ), over the entire composition range. The results obtained have been discussed and interpreted in terms of the type and nature of the specific intermolecular interactions between the components.
