The reaction of NH, with NO, is one of the potential chain-propagation steps in the combustion of ammonium dinitramide (ADN) [ l ] and in the reduction of NO, by NH, which is directly relevant to the NH, deNOx process [4-71. The reaction may occur by the following two major product channels [8-111: NH, + NO, -N,O + H,O (1) -NH,O + NO (2)
