Energetic monoanionic salts of 3,5-dinitropyridin-2-ol

Abstract

3,5-Dinitropyridin-2-ol (DNP) and thirteen of its monoanionic salts (1-13) containing diverse cations, including nitrogen-rich molecules, were readily synthesized and fully characterized by 1H, 13CNMR, and IR spectroscopy, as well as thermogravimetric differential thermal analyses, mass spectroscopy, and elemental analyses. Favorable structure-property relationships were achieved by changing the cationic moieties. The densities of the DNP salts range between 1.60-1.74gcm-3, whereas detonation velocities and pressures were calculated to be in the range 6.51-7.56kms-1 and 17.57-24.84GPa, respectively. Based on contributions to the energetic properties, the most promising cation for use in energetic DNP salts of those studied were nitroguanidine and 3-nitro-1,2,4-triazole. © 2013 WILEY-VCH Verlag GmbH & Co.
