Surface tension and density of mixtures of 1,3-dioxolane plus alkanols at 298.15 K: analysis under the extended Langmuir model

Surface tensions (sigma) for {1,3-dioxolane + methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, and 1-pentanol} and excess molar volumes (nu(E)) for {1,3-dioxolane + methanol, ethanol, 1-propanol, 2-propanol, and 2-butanol} at the temperature 298.15 K and normal atmospheric pressure have been determined as a function of mole fractions. The magnitude of these experimental quantities is discussed in terms of the nature and type of intermolecular interactions in binary mixtures. In order to analyze the surface tension behavior, the extended Langmuir (EL) model was used and the results obtained for the systems containing 1,3-dioxolane were compared with those of other formerly published series: {1,4-dioxane + alkanes} and {1,4-dioxane + alcohols}.
