Abstract

In the area of solid rocket propellants, research efforts are ongoing to find suitable oxidizers as ammonium perchlorate (AP) replacements. On the one hand, AP's performance data are excellent;on the other hand, AP and its combustion products lead to health and environmental issues. Herein, the nitraminodiacetic acid bis(2,2,2-trinitroethyl ester) (NABTNE) is presented as a green AP alternative and is compared to the bis(trinitroethyl ester) of malonic acid (MaBTNE). Simple syntheses based on economic starting materials furnished both compounds, with NABTNE having a positive oxygen balance (according to CO), a density of 1.84 g cm(-3) (@T = -118 degrees C), and a decomposition point of 180 degrees C. The density of MaBTNE (delta = 1.81 g cm(-3) @T = -147 degrees C) and the thermal stability (T-dec = 157 degrees C) are also advantageous. NABTNE as a moderately sensitive and the most promising derivative was shown to be of good stability toward long-term storage. Moreover, mixtures for a potential application in solid rocket formulations were calculated using EXPLoS (V 6.03).
