摘要：

In order to synthesis a new ionic liquid propellant with multitask mode, high density, high specific impulse, wide liquid temperature range and good thermal stability, N-methyl imidazole was used as raw material to generate ionic salt through the alkylation reaction in this article. A series of imidazolyl ionic liquids were prepared by the metathesis reaction of the ionic salt with NaBF4/LiNTf2. The products were well characterized by NMR (1H NMR, 13C NMR) and HRMS techniques. Thermal gravimetric analyzer, densitometer and viscometer were employed to test the thermal decomposition temperature, density, viscosity of these compounds. The ignition and combustion performance of the propellant prepared from hydroxylamine nitrate (HAN) and 1-ethyl-3-methyl-imidazolium ethylsulfate (EMIMEtSO4) was evaluated through a drop test by means of a high-speed camera. Chemical equilibrium and application software was applied to study the change law of HAN contents on the energy characteristics of the propellant. The results showed that the HAN contents in 40wt%~60wt% were the optimal propellant formula. It has been proved that a blend of 50wt% HAN and 50wt% EMIMEtSO4 have good catalytic decomposition and combustion performance, and is a new multitask mode ionic liquid propellant with potential application. © 2020, Editorial Department of Journal of Propulsion Technology.
