The thermal response of concentrated hydroxylammonium nitrate solutions has been studied where solutions have been brought to boiling, with only a small degree of decomposition being noted over protracted time periods. Boiling points were related to molar concentration and the decomposition gases N2 and N2O were measured to be in the ratio of 12. Also, the boiling point for propellant 1845 was measured to be 127 C, which is in agreement with previous vapor pressure extrapolations.
