xexp1 is the experimental solubility of IHI in DMF + ethanol binary solvent system, and x02 denotes the initial mole fraction of DMF in the binary solvent mixture. xApelblat1, xYaws1, xSun1, and xJA1 represent the calculated solubilities using the modified Apelblat model, Yaws model, Sun model, and modified Jouyban–Acree model, respectively. The standard uncertainty of temperature is u(T) = 0.05 K, and the relative standard uncertainty of pressure is ur(P) = 0.05. The relative standard uncertainty of mole fraction solubility is ur(x1) = 0.03, and the relative standard uncertainty of the solvent composition is ur(x20) = 0.0002.
