Abstract : The report summarizes a six month period of research on the relationship between detonation phenomena, chemical structure and kinetics for dinitroalkanes, sponsored by the Office of Naval Research. Research is being carried out on the effect of static high pressure on the rates and products of decomposition of 2,2-DNP (dinitropropane) at 190C under autogeneous pressure of 900 torr. Reaction is autocatalytic and produces acetone, acetic acid, CO2 and N2 with lesser amounts of N2O and CO; water is assumed to be present in major amounts. Decompositions were carried out from 3 to 90 per cent. Acetone appears to be formed via a simple first order process along with NO2 and NO both of which are rapidly consumed in subsequent autocatalytic oxidation reduction steps involving 2,2-DNP and its daughter fragments. A theoretical model which accounts for the autocatalytic features of the reaction, the extensive oxidation of carbon and reduction of nitrogen involves formation of oxygen from NO and NO2 and is key intermediate for subsequent chain branching steps.
