“…Literature survey indicates that, few experimental works have been performed to study thermophysical properties of drugs in different alcohols solutions. In this way, Li et al measured the density and refractive indices of hexane-1,2,3,4,5,6-hexol in aqueous solutions of 1-propanol and 2-propanol, and Chen et al have also studied 7-hydroxy-4-methylcoumarin’s viscometric, volumetric, and refractive index behavior in aqueous ethanol or 1-propanol solutions in different temperature ranges.…”

Thermophysical properties including densities and viscosities of naringenin in aqueous solutions of ethanol/1-propanol with alcohol concentrations of (24.00 to 40.00) mol•kg −1 have been measured as a function of concentration of naringenin at temperatures from (293.15 to 323.15) K and atmospheric pressure. Also, refractive indices for studied systems have been determined at 298.15 K. The measured data were used to calculate the apparent molar volume (V ϕ ), standard partial molar volume (V ϕ 0 ), partial molar volume (V̅ ), viscosity B-coefficients, and molar refractions (R m ). The viscosity and refractive index data have been analyzed by Jones−Dole and Lorentz−Lorenz equations, respectively. The trends of variation of experimental and calculated parameters have been discussed according to the interactions between solvents and solute. The obtained results imply that naringenin acts as a structure maker in the studied system.

“…Solution behavior of drugs has been extensively investigated in the last decades with the aim to explore their physiological action. − The use of volumetric properties of solution, especially apparent molar volume ( V ϕ ) and limiting partial molar volume ( V ϕ 0 ), is proven to be a well-recognized method to study the intermolecular interactions among drug and solvent molecules in fluids. , Meanwhile, the structure making/breaking ability of a drug can be analyzed by virtue of viscometric approach . In addition, the refractive index of drugs in aqueous solutions is another thermodynamic parameter to determine the interactions involved in aqueous systems.…”

Densities and viscosities of the pseudo binary system 7-hydroxy-4-methylcoumarin + (ethanol or 1-propanol) + water at temperatures of (293.15, 298.15, 303.15, 308.15, and 313.15) K and refractive indices of this system at T = 298.15 K have been measured as a function of the molality of 7-hydroxy-4-methylcoumarin. The density data have been used to compute the apparent molar volume and limiting partial molar volume. The viscosity B-coefficients and variation of B with temperature have been calculated from the viscosity data according to the Jones–Dole equation. Molar refractions of the investigated system have been obtained from the refractive index data. These parameters and their variation tendencies have been expounded in terms of the interactions between solutes and solvents. The results have shown that 7-hydroxy-4-methylcoumarin plays a structure-making role in the given solution.

“…The studies of the apparent and partial molar volumes of aqueous mixtures were used to examine solute–solvent, solute–solute, and solvent–solvent interactions, that is, they could provide useful information on the nature of interaction between solute and solvent molecules. − The apparent molar volumes ( V φ ) of EGCG were calculated from eq ,,, where M is the molar mass of the solute (EGCG), m is the molality of EGCG, and ρ and ρ 0 are the densities of solution and solvent (MCl + H 2 O), respectively. The calculated values of V φ along with ρ and ρ 0 are listed in Table and plotted in Figure S2 in Supporting Information as well.…”

Epigallocatechin gallate (EGCG) is the most abundant and active components in tea. In this text, the density and viscosity of ternary aqueous solution of EGCG containing LiCl/NaCl/KCl were determined at temperatures ranging from 288.15 to 308.15 K at atmospheric pressure. The density data was used to compute the apparent molar volumes (V φ ), limiting partial molar volumes (V φ 0 ), and transfer partial molar volumes (Δ trs V φ 0 ). The viscosity B-Coefficients were calculated from the measured viscosity data using the extended Jones−Dole equation. The values of density and viscosity increased continuously with the increasing of molality of EGCG and decreased with the temperature increasing. The positive values including (V φ , V φ 0 , Δ trs V φ 0 , viscosity B-Coefficients, the free energies of activation for solvent Δμ 1 0≠, and for solute Δμ 2 0≠) and Helper's constant (∂ 2 V φ 0 /∂T 2 ) p close to zero indicated the presence of strong solute−solvent interactions and the structure− making effect of EGCG in the investigated solutions. The apparent molar isobaric expansions (E φ 0 ) decreasing with temperature suggested that the solute−solvent interactions became weaker as temperature increased. These significant parameters could provide necessary data about molecular interactions occurring in simulated body fluids.
