Abstract : The report summarizes a six-month period of research on the relationship between detonation phenomena, chemical structure, and kinetics for dinitroalkanes. Research on dinitroalkanes is being carried out in three areas: high velocity detonation (HVD), low velocity detonation (LVD), and static high pressure and kinetic effects. Calculated and experimental failure diameters for several high-energy liquids including dinitroalkanes agree with a factor of ten. Failure wave velocity, a key variable of failure diameter theory, is related to the rate of release of chemical heat. The dinitroethanes (DNE) have similar HVD gap sensitivities but 1,2-DNE has a lower LVD gap sensitivity which is consistent with a higher activation energy for C-N bond cleavage and with LVD sensitivity order previously found for NF compounds. Thermal decomposition of 1,1-DNP (dinitropropane) is examined. (Modified author abstract)
