Thermal decomposition of neat NH{sub 4}NO{sub 3} has been the subject of many investigations over the past years. The reaction process is surprisingly complicated and depends largely on the reaction environment. For example, trace amounts of NH{sub 3}, HNO{sub 3} and H{sub 2}O are shown to affect the reaction significantly. In this research, NH{sub 4}NO{sub 3} decompostion was investigated in supercritical water. Reactions were evaluated in the presence of additional components such as organic compounds (CH{sub 3}OH, CH{sub 3}COOH, phenol), KN(NO{sub 2}){sub 2}, H{sub 2}O{sub 2}. Experiments were performed at varying temperatures, reaction times, NH{sub 4}NO{sub 3}, H{sub 2}O{sub 2} and organic compound concentrations. Gaseous, liquid and solid products were collected and analysed. The experimental results provided insight of the reaction chemistry which will be discussed in detail.
