In this paper, the solubility of methanesulfonamide (MSAM) in selected 13 pure solvents including 9 alcohols (methanol, ethanol, n-propanol, iso-propanol, n-butanol, sec-butanol, iso-butanol, n-pentanol, and iso-pentanol) and 4 esters (ethyl acetate, propyl acetate, iso-propyl acetate, and methyl propionate) at atmospheric pressure and temperatures from 283.15 to 323.15 K was determined. The solubility as a function of temperature was regressed using modified Apelblat, Van’t Hoff, λh, Wilson, and nonrandom two-liquid (NRTL) models. Based on the experimental and the simulation results, the thermodynamic mixing properties of the solutions, mixing Gibbs energy, enthalpy, and entropy were evaluated.

In this work, the solubility of bezafibrate in 16 pure solvents including 9 alcohols (methanol, ethanol, n-propanol, iso-propanol, n-butanol, iso-butanol, sec-butanol, 1-pentanol, and iso-pentanol), 4 alkyl acetate (ethyl acetate, n-propyl acetate, n-butyl acetate, and methyl propionate), 2 ketones (methyl ethyl ketone and cyclohexanone) and one nitrile (acetonitrile) and in binary mixed solvents (methanol + acetonitrile) at temperature of 283.15–323.15 K was determined. The solubility of bezafibrate in pure solvents was simulated using modified Apelblat, Van’t Hoff, Wilson, and NRTL model. That in binary mixed solvents was simulated using the modified Apelblat and Apelblat–Jouyban–Acree model. The thermodynamic mixing properties (ΔmixG, ΔmixH, ΔmixS, γ1∞, and H1E,∞) of the bezafibrate-pure solvent systems were evaluated based on the solubility data and Wilson model.

In this study, the data on solid–liquid equilibrium of 4-[2-(N-methylcarbamyl)-4-pyridyloxy]aniline were studied by the gravimetric method. The solubility of 4-[2-(N-methylcarbamyl)-4-pyridyloxy]aniline was measured in 10 pure solvents (ethyl acetate, tetrahydrofuran, acetonitrile, dichloromethane, acetone, methanol, acetylacetone, n-propanol, n-butanol, and water) and three binary solvent mixtures (water + tetrahydrofuran, acetone + n-butanol, and ethyl acetate + n-propanol) in the temperature range of 278.15 to 323.15 K under atmospheric pressure. The experimental results show that the solubility of 4-[2-(N-methylcarbamyl)-4-pyridyloxy]aniline in the abovementioned solvents increases with the increase of temperature. Among the 10 pure solvents, ethyl acetate has the highest solubility. The improved Apelblat model, Buchowski–Ksiazaczak λh model, Redlich–Kister (CNIBS/R-K) model, and Jouyban–Acree model are used for nonlinear fitting of experimental data, and the KAT-LSER model is also used to study the relationship between the solubility of 4-[2-(N-methylcarbamyl)-4-pyridyloxy]aniline in pure solvents and the interaction between solvent and solute molecules. The physical and chemical information of 4-[2-(N-methylcarbamyl)-4-pyridyloxy]aniline provided in this report may help its extraction/separation, recrystallization, purification, and formulation development.

Solubility of melatonin in twelve mono-solvents including seven alcohols {methanol (MT), ethanol (ET), n -propanol ( n -PrA), n -butanol ( n -BT), i -butanol ( i -BT), n -pentanol ( n -PT) and n-hexanol ( n -HeA)} and five esters {methyl acetate (MeAC), ethyl acetate (EtAC), n -propyl acetate ( n -PrAC), n -butyl acetate ( n -BtAC) and n -pentyl acetate ( n -PtAC)} was determined by laser monitoring approach from 278.15 K to 323.15 K under 0.1 MPa. The experimental results indicate that the mole solubility of melatonin shows a positive relation with temperature variation. The solubility of melatonin in the twelve pure solvents at 298.15 K has order: MT (0.03570) > ET (0.02536) > n -PrA (0.01965) > n -BT (0.01524) > n -PT (0.01450) > i -BT (0.01267) > n -HeA (0.01136) > MeAC (0.008498) > EtAC (0.006587) > n -PrAC (0.004280) > n -BtAC (0.003410) > n -PtAC (0.02990). Moreover, the miscibility behavior of melatonin was further analyzed by the Hansen solubility parameter (HSP). The solvent effect of melatonin in tested pure solvents was investigated by using the KAT-LSER model. The four thermodynamic models including two-Suffix Margules, NRTL, NRTL-SAC and UNIQUAC models were applied to correlate the experimental solubility data of melatonin. Furthermore, the dissolution thermodynamic properties including the apparent standard dissolution enthalpy (Δ dis H o ), the apparent standard dissolution entropy (Δ dis S o ) and the apparent standard Gibbs energy change (Δ dis G o ) of melatonin in investigated solvents were calculated by van't Hoff equation.
