2,4,6,8,10,12-Hexanitro-2,4,6,8,10,12-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.
