“…Hence, for clarity, Figure 2 shows the mass loss data for respective compounds in comparison with the benchmark [Hmim]NO 3 compound. Mass loss curves in these standard experiments (atmospheric pressure, closed crucibles with pierced lids, 5 K min −1 rate) represent the combination of vaporization and thermal decomposition [35,36] . Nevertheless, some comparative analysis can be drawn on this data.…”

The development of liquid energetic fuels with improved properties is an important topic in space propulsion technologies. In this manuscript, a series of energetic ionic liquids incorporating a 1,2,5‐oxadiazole ring and nitrate, dicyanamide or dinitramide anion was synthesized and their physicochemical properties were evaluated. The synthesized compounds were fully characterized and were found to have good thermal stabilities (up to 219 °C) and experimental densities (1.21–1.47 g cm−3). Advantageously, 1,2,5‐oxadiazole‐based ionic liquids have high combined nitrogen‐oxygen contents (up to 64.4 %), while their detonation velocities are on the level of known explosive TNT, and combustion performance exceeds those of benchmark 2‐hydroxyethylhydrazinium nitrate. Considering the established hypergolicity with H2O2 in the presence of a catalyst, and insensitivity to impact, synthesized ionic liquids have strong application potential as energetic fuels for space technologies.

“…Differential scanning calorimetry (DSC) at elevated pressure of 2.0 MPa has been applied to shift vaporization toward higher temperatures and enable the observation of thermal decomposition of materials. 16 By the decomposition extrapolated onset at 5 K min −1 rate, methylazasydnone (189 °C) lies between 4 (180 °C) and methyltetrazoles 2, 3 (214 and 225 °C, respectively). Several heating rates were applied to 1 to obtain the non-isothermal data, and the subsequent thermokinetic modeling was performed in accordance with the ICTAC recommendations 17 (further details can be found in the Supporting Information).…”

Energetic ionic liquids (EILs) have drawn considerable attention as potential liquid propellant components. However, most known EILs are oxygen-deficient and can be used only with external oxidizer. Herein, we report the first example of energetic mesoionic liquid, 3-methylazasydnone, that can function both as a monopropellant and in bipropellant systems. Methylazasydnone has the highest density among the methylated five-membered aromatic heterocycles in the liquid and solid state (1.49 and 1.60 g cm −3 , respectively), shows moderate volatility, good thermal stability, and is insensitive to impact. The computed performance of liquid propellant's combustion is superior to that of the benchmark energetic ionic liquid, 2hydroxyethylhydrazinium nitrate (428 vs 424 g•s cm −3 ). Overall, methylazasydnone is a promising advanced functional material for application in green liquid mono-and bipropellants.
