Energetic Metal and Nitrogen-Rich Salts of the Pentaerythritol Tetranitrate Analogue Pentaerythritol Tetranitrocarbamate.

The tetravalent pentaerythritol tetranitrocarbamate (PETNC) is deprotonated by nitrogen-rich, alkaline, alkaline earth metal, and silver bases to form the corresponding salts. Thorough analysis and characterization by multinuclear NMR, vibrational spectroscopy, elemental analysis, thermoanalytical techniques, and single crystal X-ray diffraction was performed. Furthermore, the energies of formation for the nitrogen-rich salts were calculated utilizing the Gaussian program package. The detonation performances were calculated with the Explo5 (V6.03) computer code, and the sensitivities toward impact and friction were determined and compared to the neutral PETNC and pentaerythritol tetranitrate (PETN). Ecotoxicological studies of the ammonium and guanidinium salt using Vibrio fischeri bacteria complete this study.
