“…According to literature, dissolution thermodynamic properties can be calculated by the following equations for a nonideal system. The %ξ H and %ξ S , which represent the comparison of the relative contribution to the standard Gibbs energy by enthalpy and entropy in the solution process, respectively, , are define by the following two equations: The calculated dissolution enthalpy, entropy, and Gibbs energy, together with %ξ H , %ξ S calculated under the experimental temperature, are shown in Table . According to the data in Table , it can be seen that the values of Δ G dis are negative in all selected solvents, indicating that the dissolution process of DNP is a spontaneous process.…”

The solubilities of 3,4-dinitro-1H-pyrazole (DNP) in different solvents are essential for crystallization and further theoretical studies. In this paper, the solubilities of DNP in six pure solvents were determined in temperatures ranging from 298.15 K to 338.15 K by the dynamic laser monitoring method under atmospheric pressure. The results showed that the solubility of DNP in each tested solvent increases with the increasing temperature. Melting temperature T m and fusion enthalpy ΔH fus of DNP were determined using differential scanning calorimetry. Solubility data was correlated by the modified Apelblat equation, λh equation, Wilson model and nonrandom two-liquid (NRTL) model, and these results showed that all models can give satisfactory correlation results. Therefore, the experimental data and model parameters would provide essential support for industrial design. Furthermore, on the basis of the NRTL model and solubility data, the dissolution thermodynamic properties, including enthalpy, entropy, and Gibbs energy were determined.

“…To describe the effect of both solvent compositions and temperature on the solubility of naringin, another model called Jouyban-Acree model was adopted, which is perhaps one of the more versatile models to describe the solubility of a solute with the Table 2 Parameters of Apelblat equation for naringin in the binary solvent system of ethanol and water and the root-mean-square deviations. variation of both temperature and initial composition of binary solvent mixtures [21,22]:…”
