Decreasing the hygroscopicity of ammonium dinitramide (ADN) through cocrystallization
To decrease the hygroscopicity of ADN—a energetic oxidizer, this study developed a new cocrystal composed of ADN and 18C6 (18-crown-6) at a 1:1 M ratio through cocrystallization using the solvent evaporation method. The structure of the ADN/18C6 cocrystal, which has been confirmed using single X-ra...

| description | To decrease the hygroscopicity of ADN—a energetic oxidizer, this study developed a new cocrystal composed of ADN and 18C6 (18-crown-6) at a 1:1 M ratio through cocrystallization using the solvent evaporation method. The structure of the ADN/18C6 cocrystal, which has been confirmed using single X-ray diffraction (SXRD), indicates that the formation of this cocrystal is attributed to the strong intermolecular hydrogen bond interactions between ammonium ions and crown ether cycles. The ADN/18C6 cocrystal has a melting point of 151.5 °C, which is significantly higher than those of its respective components: 93.6 °C of ADN and 43.2 °C of 18C6. Notably, the ADN/18C6 cocrystal is nearly non-hygroscopic compared with ADN. The cocrystal's hygroscopicity rate is 0.9% when exposed to the air with relative humidity (RH) of 60% and a temperature of 30 °C for 12 h. By comparison, ADN's hygroscopicity rate is 18% under the same conditions. In addition, the impact sensitivity of the ADN/18C6 cocrystal is 18 J, which is substantially lower than that of raw ADN (2.5 J). These results show that cocrystallization offers an effective way to reduce the hygroscopicity of ADN. |
