The System Dioxane and Water

Raman spectroscopy of solutions and interfaces containing nitrogen dioxide, water, and 1,4 dioxane: Evidence for repulsion of surface water by NO2 gas

“…To make the experiment work, it was necessary to use a mixed solvent comprised of water and 1,4 dioxane, the purpose of the dioxane being to provide a reference surface relative to which the displacement of water could be observed. Surface tension measurements 9 indicate that 1,4 dioxane behaves as a weak surfactant in water, but this surfactant effect plays no role in our experiments, which could not resolve a surface monolayer. Dioxane was chosen as the reference substance because it is both unreactive and totally miscible with water, properties that have often been exploited by electrochemists and spectroscopists.…”

Surface Tension of Nonideal Binary Liquid Mixtures as a Function of Composition

“…Starting from the Rasmussen area at x 1,B ϭ 0, Eqs. [21] and [22] permit calculation of the partial molar surface area as a function of composition. Table 4 summarizes the results of the above calculations.…”

“…For the method of derivation of the Rasmussen areas, the reader is referred to the original source (16). The surface tension of aqueous-organic mixtures was measured by the capillary rise method using accurate temperature control to within 0.02°C (22).…”

Thermodynamics of the amalgam cell {KxHg1−x| KCl (m)| AgCl | Ag }and primary medium effects upon KCl in { ethylene glycol + water }, { acetonitrile + water }, and { 1,4-dioxane + water } solvent mixtures

“…Relative permittivities ε, (28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38) densities ρ, (28)(29)(30)(31)(32)(33) and other relevant quantities are quoted analogously to values of cells (II) and (III), respectively, it can be shown (8) that, at a given temperature T , their sum E is solely dependent on the m 2 γ ±2 /m 1 γ ±1 ratio:…”
