12-hexaazaisowurtzitane (CL-20) has the highest crystal density and detonation speed among high-energy materials and is widely used in military and aerospace industries. However, data on the solubility of γ-CL-20 are rarely reported in the open literature. Considering the solubility is important to the CL-20 crystallization process, the solubility of γ-CL-20 in six pure solvents (ethyl acetate, methanol, ethanol, n-propanol, n-butanol, isopropanol) and four binary solvents (dichloromethane + ethyl acetate, 1,2-dichloroethane + ethyl acetate, chloroform + ethyl acetate, tetrachloromethane + ethyl acetate) has been measured by the laser dynamic method in the temperature range of 283.15−323.15 K. The measured solubility data in pure solvents were fitted by the Apelblat equation, the Yaws model, and the polynomial empirical equation. The Apelblat equation, the Yaws model, and the modified Jouyban−Acree model were adopted to correlate the experimental solubility data in four binary solvents. This work can guide further crystallization research of γ-CL-20.

The solubilities of 3-aminophenol in monosolvents (ethyl acetate, isopropyl acetate, n-butyl acetate, amyl acetate, 1,2-dichloroethane, trichloromethane, benzene, 1,4-dioxane, tetrahydrofuran, and acetonitrile) and binary solvent mixtures (1,4-dioxane + water, tetrahydrofuran + water, and acetonitrile + water) were determined by a static gravimetric method at temperatures ranging from 283.15 to 328.15 K under atmospheric pressure. The solubility of 3-aminophenol in all solvent systems is positively correlated with temperature. In monosolvents, the solubility order of 3-aminophenol was as follows: THF > 1,4-dioxane > acetonitrile > ethyl acetate > isopropyl acetate > n-butyl acetate > amyl acetate > 1,2-dichloroethane > trichloromethane > benzene. The maximum solubility value occurred in 1,4-dioxane (x 1 = 0.3700 mol·mol–1, T = 328.15 K), and the minimum solubility value occurred in benzene (x 1 = 0.0005505 mol·mol–1, T = 288.15 K). In general, the solubility of 3-aminophenol in 1,4-dioxane + water and THF + water is greater than that in acetonitrile + water. There is a cosolvency phenomenon of 3-aminophenol in the solvents of 1,4-dioxane + water and acetonitrile + water. The experimental solubility data were correlated by the modified Apelblat model, the Yaws model, the λh model, the Sun model, the modified Jouyban–Acree model, and the Wilson model. The modified Apelblat model best fitted the experimental data among all of the selected models in monosolvents (with relative average deviation (RAD) and root-mean-square deviation (RMSD) less than 0.0156 and 0.001212, respectively) and binary solvent mixtures (with RAD and RMSD less than 0.0102 and 0.001408, respectively). Based on the experimental data of the solubility of 3-aminophenol in mono and binary solvents, the Wilson model was used to calculate the dissolution properties (Δdis H, Δdis S, and Δdis G). The results indicate that the dissolution process of 3-aminophenol is endothermic, entropy-increasing, and spontaneous. All of the selected models for both mono and binary solvents provide satisfactory correlation results.
