N2 - The solubility of 3,7-dinitro-1,3,5,7-tetraazabicyclo [3.3.1] nonane (DPT) was measured in ethanenitrile, methanol, 1,1-dichloroethane, dimethyl sulfoxide (DMSO), acetone, ethyl acetate, ethyl acetate and methanol mixture, and acetonitrile and water mixture from 288.15 K to 308.15 K. In this paper, the determination method of DPT was first established by high-performance liquid chromatography (HPLC) with optimized chromatographic conditions. The solubility of DPT in all solvents was measured upon this chromatographic method. Experimental results show that the order of solubility can be represented as DMSO > acetonitrile > ethyl acetate > ethyl acetate/methanol (9:1, v/v) > ethyl acetate/methanol (7:3, v/v) > acetone > acetonitrile/water (9:1, v/v) > ethyl acetate/methanol (5:5, v/v) > acetonitrile/water (7:3, v/v) > 1,1 - dichloroethane > methanol. Moreover, its solubility increased with raising the temperature. The thermodynamic properties of DPT, such as solution enthalpy, have also been calculated.
