Solute–Solvent and Solute–Solute Interactions of Resorcinol in Mixed 1,4-Dioxane–Water Systems at Different Temperatures

Abstract

The densities, viscosities, and ultrasonic speeds of resorcinol in 1,4-dioxane + water mixtures and in pure 1,4-dioxane have been measured at 303.15, 313.15, and 323.15 K. Apparent molar volumes (V φ ) and viscosity B-coefficients are obtained from these data supplemented with densities and viscosities, respectively. The limiting apparent molar volumes (V 0 φ ) and experimental slopes (S * v ) derived from the Masson equation have been interpreted in terms of solute-solvent and solute-solute interactions, respectively. The viscosity data have been analyzed using the Jones-Dole equation, and the derived parameters B and A have also been interpreted in terms of solute-solvent and solute-solute interactions, respectively. The structure making/breaking capacities of resorcinol in the studied solvent systems have been discussed. The compressibilities obtained from the data supplemented with their ultrasonic speeds indicate the electrostriction of the solvent molecules around the ions.

Partial Molar Volumes, Viscosity B-Coefficients, and Adiabatic Compressibilities of Sodium Molybdate in Aqueous 1,3-Dioxolane Mixtures from 303.15 to 323.15 K

“…The apparent molar volumes (V φ ) were determined from the solution densities using the following equation [3]:…”

Partial Molar Volumes and Viscosity B-Coefficients of Nicotinamide in Aqueous Resorcinol Solutions at T = (298.15, 308.15, and 318.15) K

“…Fine Chemical Limited. Resorcinol was purified by a reported procedure [13,14], and the compound was dried and stored in a vacuum desiccator. Freshly distilled conductivity water was used for the preparation of different aqueous resorcinol solutions.…”

“…As partial molar volumes and viscosity B-coefficients of a solute provide valuable information about solute-solute, solute-solvent, and solvent-solvent interactions [11][12][13] in solutions, in this paper we attempted to study these properties for nicotinamide in aqueous solutions of resorcinol at (298.15, 308.15, and 318.15) K to explain the various interactions prevailing in the ternary systems under investigation.…”

Ion–solvent and ion–ion interactions of sodium molybdate salt in aqueous binary mixtures of 1,4-dioxane at different temperatures

“…Partial molar volumes of electrolytes at infinite dilution provide valuable information about ion-ion, ion-solvent and solvent-solvent interactions [1][2][3]. This information is of fundamental importance for a proper understanding of the behaviour of electrolytes in solution.…”

“…Measurement of ultrasonic speeds of the solutions also helps in this regard. Recently, we have undertaken a comprehensive programme to study the solvation and association behaviour of some electrolytes [3,4] in different aqueous and non-aqueous solvent media from the measurement of various transport and thermodynamic properties. Aqueous 1,4-dioxane is an important mixed solvent for a number of separation processes and solution studies [5], because of its wide-ranging relative permittivity (2.2- in aqueous 1,4-dioxane mixtures from volumetric, viscometric and acoustic measurements.…”
