Various energetic polynitro esters, carbamates, and nitrocarbamates that were derived from the amino acid glycine were fully characterized by single-crystal X-ray diffraction, vibrational spectroscopy (IR and Raman), multinuclear NMR spectroscopy, elemental analysis, and differential scanning calorimetry (DSC). Owing to their positive oxygen balance, the suitability of these compounds as potential oxidizers in energetic formulations was investigated and discussed. In addition, the heats of formation of the products were calculated by using the Gaussian09 program package at the CBS-4M level of theory. From these values and the calculated densities (from the X-ray data), several detonation parameters, such as detonation pressure, velocity, energy, and temperature, were computed by using the EXPLO5 code. Furthermore, their sensitivities towards impact, friction, and electrostatic discharge were tested by using a drop hammer, a friction tester (both BAM certified), and a small-scale electrical-discharge device, respectively. Nitrated amino acids: Amino acids are excellent starting materials for the preparation of various polynitro compounds. This study describes the extension of a previous reaction sequence for the development of new energetic materials from the amino acid glycine. Various compounds have been synthesized, fully characterized, and their potential as high-energy dense oxidizers in solid-state rocket propellants has been investigated (see figure). Copyright
