Alkyl levulinate, prepared from the esterification of levulinic acid and n-alcohol, has the potential to be used as a fuel additive. Alcohol has also been used as an additive in fuel to improve ignition and combustion characteristics to a certain extent. For this reason, the properties of mixtures containing these compounds are of particular interest. Herein, measurements of density (ρ), surface tension (γ), and refractive index (n) were conducted for three binary mixtures of methyl levulinate–methanol (ML–M), ethyl levulinate–ethanol (EL–E), and n-butyl levulinate–butanol (BL–B). These properties were measured over the entire range of compositions in 0.1 increments of the molar fraction of the components in the temperature range of T = 298.15–323.15 K and at an atmospheric pressure of p = 0.1 MPa. The experimental data were used to calculate the excess and deviation properties, that is, excess molar volumes (V m Ε), surface tension deviations (Δγ), and molar refraction deviations (ΔR). The V m Ε, Δγ, and ΔR values were fitted to the Redlich–Kister polynomial equation. The V m Ε and ΔR values were negative for all compositions, whereas Δγ exhibited both negative and positive values at different compositions. The molecular interactions of the binary mixtures are discussed from these excess and deviation functions. Furthermore, the Jouyban–Acree model was used for the correlation of properties: density, surface tension, and refractive index of the studied mixtures at different temperatures (T = 298.15–323.15 K). The results are expected to provide fundamental data for understanding the properties of alkyl levulinate as a potential bio-based fuel additive.

“…The coefficients of the Jouyban–Acree model possess physicochemical meanings and represent differences in the component–component interactions in the liquid mixtures. The main advantage of the Jouyban–Acree correlation model is that it includes the effects of temperature and provides the possibility of physical property predictions at other temperatures . The model coefficients ( A i ) for densities, viscosities, and refractive indices of the six systems are summarized in Table S9, together with the AARD.…”

Measurements on densities, viscosities, and refractive indices at atmospheric pressure for binary mixtures of 1,3-dimethyladamantane (1,3-DMA), 1,3,5-trimethyladamantane (1,3,5-TMA), and 1-ethyladamantane (1-EA) with n-nonane or n-undecane are carried out over the whole composition range at temperatures T = 293.15−343.15 K and atmospheric pressure. The excess molar volume (V m E ), deviation in viscosity (Δη), deviation in refractive index (Δn D ), and deviation in molar refraction (ΔR) for the six mixtures are calculated and then fitted to the Redlich−Kister polynomial. The V m E values are all negative over the entire range of mole fractions and decrease with increasing temperature for the six binary systems. The absolute values of Δη for the mixtures decrease obviously with increasing temperature. The Δn D values with the volume fraction for the six systems are all positive over the entire composition range. Density, viscosities, and refractive index of the six systems are correlated by the Jouyban−Acree model. The experimental results could be useful for the development of high-energy-density hydrocarbon fuels.

“…For common’s point, it would be efficient to employ classical methods, that is, cosolvents, surfactants, and cosolvents containing hydrotropy to promote solute to dissolve in water more easily. , In some degrees, cosolvency is the most effective solubilization strategy to improve the solubility of which aqueous cosolvent mixtures are essential for pharmaceutical fields in that it acted as a reaction medium during the synthesis of the drug and also removes impurities in the drug to purify the drug. ,, Solvent crystallization is a crucial step to refine the drug fenbendazole products for commercial market. Fenbendazole is almost insoluble in water resulting in the low bioavailability of oral drugs; meanwhile, drug solubility in aqueous mixtures is also required in some further pharmaceutical applications. ,, …”

Four liquid mixtures formed by mixing water and four organic solvents (methanol, ethanol, ethylene glycol, and N,N-dimethylformamide (DMF)) in different ratios were used as solvents, and fenbendazole was used as a solute. The concentration of the solute within T = 283.15–328.15 K and in different mixed solvents was determined by static techniques at p = 101.1 kPa. The experimental solubility of fenbendazole was obviously affected by the solution system temperature and organic solvent concentration. High temperature and high concentration were beneficial to the dissolution of solutes. Conversely, low temperature and low concentration hinder dissolution. In all mixture systems studied, the control of temperature and organic solvent concentration remained unchanged, and the DMF + water system was most beneficial for the dissolution of solutes. Solid powder at the bottom of the vessel when the fenbendazole dispersion process achieved dynamic equilibrium was tested by XPRD. Several thermodynamic cosolvency models Jouyban–Acree model, van’t Hoff–Jouyban–Acree model, and Apelblat–Jouyban–Acree model were employed to calculate the solubility data of fenbendazole. The calculation result has a very little error with the experimental value and the relative average deviation value of ≤2.90% and the root-mean-square deviation value of ≤1.440 × 10–3. The purpose of this work is to provide basic information and extend the library of solubility of bioactive drug fenbendazole in aqueous solutions, relevant for pharmaceutical separation, purification, and further application.
