“…The Jouyban–Acree model can be used to correlate the physicochemical properties such as densities and viscosities with respect to the composition at different temperatures. , The major advantage of the Jouyban–Acree model is that it includes the effects of temperature in the model constants and provides the possibility of physicochemical property predictions at different temperatures using the interpolation technique . The Jouyban–Acree model for representing the densities or viscosities of binary systems is expressed as where y m , T , y 1, T , and y 2, T represent the densities or viscosities of binary mixtures and components 1 and 2 at temperature T , respectively; x 1 and x 2 are the molar fractions of components 1 and 2, respectively; A i represents the model constants obtained by regressing (ln y m, T – x 1 ln y 1, T – x 2 ln y 2, T ) against x 1 x 2 / T , x 1 x 2 ( x 1 – x 2 )/ T , and x 1 x 2 ( x 1 – x 2 ) 2 / T using a no intercept least squares.…”

exo-Tetrahydrodicyclopentadiene can serve as both the propellant and coolant in hypersonic vehicles. However, its applications are restricted by the poor properties of ignition and combustion to some extent. Fuel additives such as appropriate alcohols have the ability to overcome these deficits. Research on thermophysical properties of the mixtures composed of exo-tetrahydrodicyclopentadiene and fuel additives can provide important information for the research of fuel additives. In this work, densities and viscosities of the ternary system of exotetrahydrodicyclopentadiene (1) + n-decane (2) + iso-butanol (3) and three corresponding binary systems have been measured over the whole composition range in the temperature range from 293.15 to 333.15 K with an interval of 5 K and at pressure p = 0.1 MPa. The values of excess molar volumes (V m E ) and viscosity deviations (Δη) of three binary systems and the ternary system were calculated and then fitted to the Redlich−Kister equation and four semiempirical equations, respectively. The variations of V m E and Δη were explained from the viewpoints of intermolecular forces and structural effects. Furthermore, the Jouyban−Acree model was used to correlate the values of densities (ρ) and viscosities (η) of the studied mixtures with high accuracy.

“…The density of the {PEG (1) + water (2)} cosolvent mixtures at 298.2 K was taken from the literature. 27,28 The density of both saturated solutions and cosolvent mixtures as well as the apparent specific volumes of sucrose at 298.2 K are presented in Table 3. Figure 2 allows the visual comparison of densities for all the saturated solutions and the cosolvent mixtures free of solute.…”

Background: Sucrose is the most widely used sweetener in food and pharmaceuticals. Quantitative solubility values of this excipient in aqueous polyethylene glycol (PEG) mixtures is not abundant. Thus, the main objective of this research was to determine and correlate the equilibrium solubility of sucrose in {PEG 200 (or 400) + water} mixtures at 298.2 K. Methods: Shaken flask method was used to determine isothermal solubility. Concentration measurements were performed by means of density determinations. Jouyban-Acree model was used to correlate both solubility sets. Results: Solubility of sucrose decreases non-linearly with the addition of either PEG200 or PEG400 to water. Jouyban-Acree model correlates solubility values with mixtures composition for both cosolvent systems. Moreover, apparent specific volume of sucrose were also calculated from density and compositions. Conclusion: Useful solubility values of sucrose at equilibrium in aqueous mixtures of PEG200 and PEG400, as well as their volumetric contributions to saturated solutions are reported.

The solubility of drugs in cosolvent systems of pharmaceutical interest is of great importance for understanding and optimizing a large number of processes. Here, we report the solubility of isoniazid in nine (PEG 200 + water) cosolvent mixtures at nine temperatures (278.15, 283.15, 288.15, 293.15, 298.15, 303.15, 308.15, and 318.15 K) determined by UV–vis spectrophotometry. From the solubility data, the thermodynamic solution, mixing, and transfer functions were calculated in addition to performing the enthalpy–entropy compensation analysis. The solubility of isoniazid depends on the concentration of PEG 200 (positive cosolvent effect) and temperature (endothermic process) reaching its maximum solubility in pure PEG 200 at 318.15 K and the lowest solubility in pure water at 278.15 K. The solution process is favored by the solution entropy and according to the enthalpy–entropy compensation analysis it is driven by entropy in mixtures rich in water and by enthalpy in mixtures rich in PEG 200.
