Hydroxylammonium nitrate (HAN), as a tentative candidate to replace hydrazine, has been exten-sively studied by several research groups. Indeed, studies of its thermal decomposition in liquid state have been performed via online and real-time analysis. Advanced thermal analysis has been carried out using the direct insertion probe–mass spectrometry (DIP–MS) technique with higher tempera-ture ramp of 128°C min^–1 . A pyrolizer was used to decompose the HAN solution at 280°C, and the detected gases were analyzed online. On the other hand, the theoretical aspects have completed the experimental data by using the differential function theory (DFT) to explain the thermal decomposition mechanism at the gas and liquid phases of HAN base, and to see the effect of water as a solvent on HAN reactivity and the energy diagrams.
