“…Previously, the properties of 1,4-DO solutions have been repeatedly studied by many experimental and theoretical methods, and thanks to these works, the structure and some properties related to the structure were determined. To study 1,4-DO aqueous mixtures, X-ray diffraction; − neutron diffraction; − NMR, ,, IR, and Raman spectroscopy; MD simulations; time-resolved fluorescence spectroscopy; dielectric relaxation; calorimetry; viscometry; and densimetry were used. ,− However, despite the availability of a large amount of literature data on the volumetric properties of the water + 1,4-DO mixture, there are still some contradictions. ,, The present study will clarify some values and significantly expand our knowledge of the properties of this system, especially since the measurements were carried out in a wider temperature range.…”

The densities of the mixture {water (1) + 1,4-dioxane (2)} were measured using a vibration density meter at temperatures from 274.15 to 333.15 K and atmospheric pressure over the entire composition range. The excess molar volume of the mixture and the partial molar volumes of water and 1,4-dioxane were calculated. The temperature of the maximum density of 1,4-dioxane aqueous solutions was determined. It is shown that the formation of the mixture occurs with a decrease in volume. The dependences of partial molar volumes on the concentration of water and 1,4-dioxane have extremums. The values of molar volumes of water and 1,4-dioxane exceed the corresponding limit partial molar volumes. An increase in the temperature or concentration of 1,4-dioxane increases the magnitude of the molar expansion of the mixture over the entire range of compositions. Replacing the intrinsic environment of a molecule in a solvate shell with molecules of another component leads to a decrease in the partial molar volume at infinite dilution. The obtained results were compared with the literature data.
