Monomethylhydrazinium nitrate was synthesized by mixing the hypergolic bipropellant monomethylhydrazine and nitric acid under nonignition condition. The burn rate of this nitrate-based monopropellant is studied by using a high-pressure strand burner with optical access, coupled with a high-speed camera for capturing and analyzing the combustion characteristics. In addition, pyrolysis of this energetic material was investigated by a confined rapid pyrolysis setup with heating rates on the order of 2000 K/s, coupled to a rapid-scan Fourier transform infrared spectroscope. The decomposition mechanism of monomethylhydrazinium nitrate is discussed.
