Guanidinium Dicyanamide-Based Nitrogen-Rich Energetic Salts as Additives of Hypergolic Ionic Liquids
In this paper, four kinds of guanidinium dicyanamide-based energetic salts were prepared and investigated as energetic additives to hypergolic ionic liquid 1-ethyl-3-methyl imidazolium dicyanamide ([EMIM] [DCA]) for the first time. Their densities, viscosities, heat of formation, specific impulse, ignition delay time, melting point, charge distribution, and decomposition temperature were tested and calculated. The results showed that these salts possessed high nitrogen content (>66 wt %), high density, and high specific impulse. Their addition can bring significant improvement in the density and specific impulse of [EMIM] [DCA] and hardly affect its ignition delay time.
