And the article was included in Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) in 2017.COA of Formula: C5H6ClN This article mentions the following:
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 phys. and chem. 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, resp., 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. In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7COA of Formula: C5H6ClN).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.COA of Formula: C5H6ClN
