Abstract

A solid oxidizer pyridinium dinitramide (Py-DN) has been newly synthesized as a low toxic chlorine-free energetic oxidizer. The reaction yield increased by 10% higher than the other dinitramide such as ADN because Py-DN was directly converted without sequential precipitation of intermediates. A thermal analyzer, a UV–visible spectrometer and a Fourier transform-infra-red spectrometer were used to characterize the physical and chemical properties of the synthesized Py-DN, and the results were compared with previously prepared salts of ammonium dinitramide (ADN, NH₄N(NO₂)₂) and guanidine dinitramide [GDN, NH₂C(NH₂)NH₂N(NO₂)₂]. The characteristic endothermic and exothermic decomposition temperatures of Py-DN were 77.4 °C and 144.7 °C, respectively, and the material had a combustion caloric value of 1,739 J/g. These low values indicate that Py-DN is more thermally sensitive than the conventional dinitramides. Furthermore, it enables to decrease the decomposition temperature, which can reduce preheating temperature required for thruster operation.
