The solubility of bisphenol A in binary solvents (ethyl acetate + n-butanol, ethyl acetate + 2-butanol, ethanol + n-butanol, and ethanol + 2-butanol) was measured by a laser dynamic method under p = 101.1 kPa at temperatures ranging from 273.15 to 313.15 K. The solubility increased with increasing temperature at a given solvent composition; the solubility also increased with increasing content of ethyl acetate or ethanol at a given temperature. The modified Apelblat equation, λh equation, and Sun model were used to correlate the experimental solubility data; the values of RD and rmsd indicated that these models fitted the solubility data well.

“…In addition, the modified Apelblat model was used to correlate the solubility of three compounds in water at different temperatures. It is a semi-empirical model to correlate the mole fraction solubility with temperature T and it is shown in eq . , x represents the mole solubility of uric acid, adenine, or guanine in water, and parameters A , B , and C are adjustable parameters of the model. The parameter A and B reveal the influence of solution nonideality upon the solute solubility and the variation of the solute activity coefficient, respectively.…”

In this work, nine ternary phase diagrams and three quaternary phase diagrams of different systems at 298.15, 308.15, and 318.15 K were constructed. The ternary solid–liquid phase equilibrium of (uric acid + adenine + water), (uric acid + guanine + water), and (adenine + guanine + water) and quaternary solid–liquid phase equilibrium of (uric acid + adenine + guanine + water) were determined at atmospheric pressure (p = 101.3 kPa). The binary solubility of uric acid, adenine, and guanine in water at different temperatures was determined and correlated using the modified Apelblat model, and the mole solubility of adenine was about 30 and 180 times that of uric acid and guanine, respectively. The relative average deviation and root-mean-square deviation values were no more than 1.73 × 10–2 and 0.102 × 10–5, respectively. For a ternary system, each phase diagram consisted of one cosaturated point, two cosaturated solubility curves, and three solid-phase regions (two single solid-phase regions and one double solid-phase region). The mutual solubility of uric acid (adenine or guanine) in the systems of (uric acid + adenine + water), (uric acid + guanine + water), or (adenine + guanine + water) increased with increasing temperature. The unsaturated regions enlarged, and the single or double solid-phase regions diminished. For a quaternary system, each Janeck projection of the (uric acid + adenine + guanine + water) system consisted of one cosaturated point, three cosaturated solubility curves, and three solid-phase regions. At the same temperature, the solid-phase regions of three compounds were ranked as guanine > uric acid > adenine. The construction of binary, ternary, and quaternary phase diagrams of uric acid, adenine, and guanine in water was of great significance for studying the deposition of uric acid, and this can also provide reference and basic phase equilibrium data for further study of gout treatment and effects of uric acid on the cardiovascular system.

In this study, the solubility data of 18β-glycyrrhetinic acid (GA) in 12 neat solvents were determined by the static equilibrium method at a temperature range of 278.15–323.15 K under a pressure of 0.1 MPa. These selected solvents were methanol, ethanol, n-propanol, isopropanol, methyl acetate, propyl acetate, butyl acetate, isobutyl acetate, acetone, 1,4-dioxane, N,N-dimethylformamide (DMF), and tetrahydrofuran (THF). The experimental results showed that the solubility of GA was positively correlated with temperature and was correlated using thermodynamic models. Activity coefficient models such as the NRTL model, Wilson model, Margules model, and van Laar model were applied to fit the experimental solubility of GA. A good relevance can be obtained for data fitting using these models, and the best fitting effect was achieved with the Wilson equation from ARD and R 2. The Hansen solubility parameter was applied to explain the GA solubility phenomenon in pure solvents. These study results contribute to crystallization operation of GA for purification and separation.
