Although it is generally accepted that the principle initial step in the decomposition of ammonium perchlorate is proton transfer, details of the subsequent reactions have not been resolved. In this report, full use is made of recently published data on perchloric acid and chlorine dioxide flames, on the oxidation of ammonia, on the reactions of nitroxyl and on the reactions of the chlorine oxides, to deduce a detailed mechanism for the chemical decomposition of ammonium perchlorate. Whilst emphasis has been given to the high temperature decomposition, the basic mechanism is adaptable to a wide range of conditions to the low temperature decomposition, to combustion, to the catalysed decomposition and to decomposition under various reactive gases. The central feature of the mechanism is that, in the decomposition of ammonium perchlorate, ammonia is oxidized principally by the ClO radical.
