Replacement of Toxic Hydrazines in Satellite Propulsion with Greener Dinitramide-based Energetic Ionic Liquid Candidates

In this study we evidence green formulations that retain high propulsive performances. They are based on the dinitramide anion. From an initial library of 37 ammonium dinitramides 3 best candidates were selected after evaluation of their potential syntheses, calculated theoretical performances, experimental synthesis optimizations and decomposition temperatures. These three salts were then formulated to obtain acceptable sensitivities and melting points, which eventually led to only one formulation being retained: a 40:60 mixture of dimethylammonium dinitramide and ammonium dinitramide phlegmatized by 10% of glycerol.PMID:38533907 | DOI:10.1002/chem.202303965
