The Electrolysis of Ammonium Dinitramide in Dimethyl Sulfoxide [PDF]

Propellants, Explosives, Pyrotechnics, 2020
AbstractThis work investigated the electrolysis of ammonium dinitramide (ADN: NH4N(NO2)2) in dimethyl sulfoxide (DMSO). Various fundamental electrolysis properties of ADN were assessed based on an electrochemical study and the associated mechanisms were examined based on a quantum chemical approach.

Decreasing the hygroscopicity of ammonium dinitramide (ADN) through cocrystallization

Energetic Materials Frontiers, 2022
To decrease the hygroscopicity of ADN—a energetic oxidizer, this study developed a new cocrystal composed of ADN and 18C6 (18-crown-6) at a 1:1 ​M ratio through cocrystallization using the solvent evaporation method.
