To reduce the acidity defect of 4,8-dihydrodifurazano[3,4-b,e]pyrazine(DFP), a new energetic ionic compound aminourea salt of 4,8-dihydrodifurazano[3,4-b,e]pyrazine (DSDFP) was designed and synthesized with a yield of 72.6%. The structure of target compound was characterized by means of NMR ( 1 H and 13 C), IR spectra, elemental analysis and single crystal X-ray diffraction. The thermal stability was tested by DSC and TG method and DSDFP shows good thermal stability with exothermic decomposition peaks in the range of 267.3 °C ∼ 282.3 °C. The impact sensitivity was measured using BAM standard method and the detonation performance was computed by Kamlet-Jacobs equations. Results show that DSDFP exhibits excellent impact sensitivity of greater than 40 J and desirable detonation performance with detonation velocity of 7891 m/s and detonation pressure of 27.1 GPa. These results highlight its great promise of potential candidates for high-performance energetic salt.
