1-Amino-1-hydrazino-2,2-dinitroethene and Corresponding Salts: Synthesis, Characterization, and Thermolysis Studies

Synthesis, characterization, and thermolysis studies of 1-amino-1-hydrazino-2,2-dinitroethene (2) and salts thereof are reported. These compounds have been fully characterized by IR and NMR spectroscopy, elemental analysis, differential scanning calorimetry (DSC), density, and impact sensitivity measurements. Compound 2 decomposes at 124.5 degrees C (DSC) and the salts decompose over the range 138.6-181.6 degrees C, thus showing higher thermostability. The calculated detonation pressures (P) for these salts range from 27.2 to 37.8 GPa, and detonation velocities (vD) fall between 8424 to 9482 m s(-1); these properties make them competitive energetic materials.
