Synthesis and performance analysis of ammonium dinitramide [PDF]

, 2017
Ammonium dinitramide as non-corrosive, high performance, and Eco-friendly propellant was first synthesized by Russians in early 1970s, and then independently in early 1990s by Stanford Research International. Since then, there has been increased interest

Safety of Ammonium Dinitramide Synthesis vs. Size of a Commercial Production Scale

, 2015
Ammonium dinitramide (ADN) is an ecological oxidizer suggested as a substitute for ammonium chlorate(VII) in solid rocket fuels. Three ADN synthetic methods were studied in order to estimate process safety under increased production scale, viz.: from ...

ASSESSMENT OF THE SYNTHESIS ROUTES CONDITIONS FOR OBTAINING AMMONIUM DINITRAMIDE BY THE FT-IR. DOI: 10.5028/jatm.2011.03033311

Journal of Aerospace Technology and Management, 2012
Over the last two decades, many routes have been proposed to synthesize ammonium dinitramide (ADN). However, most of them lie in routes in which reactants are too expensive for large-scale production.
