Abstract : A summary of some characteristics of various liquid propellants has been given by Klein. In the present report, attention is focused on hydroxylammonium nitrate, which is the more important component in HAN-based propellants. Under ambient conditions, this salt can be dissolved in H20 up to 95% by weight. The concentration most often used in the present report is 11 molar (73.6%). Both ions of HAN are oxygen-rich and therefore the predominant mode of reaction with most other compounds is oxidation (1). Although HAN is a propellant by itself, the fuel component isopropylammonium nitrate (IPAN) is often used in a mixture under various conditions. Slow reaction sequences were also monitored using Raman spectroscopy. To obtain the spectral assignments, the sample was contained in a glass capillary tube. The Raman spectrum of various related compounds, such as ammonium nitrate, was also obtained for reference purposes.
