The report summarizes research on the relationship between detonation phenomena, chemical structure, and kinetics for isomeric dinitropropanes and other nitroalkanes. Research on dinitropropanes is being carried out in three areas high velocity detonation HVD, low velocity detonation LVD, and static high pressure and kinetic effects. Smooth-shock reaction times measurements on 1,1-DNE dinitroethane 1,1,1-FDNE fluorodinitroethane, 1,1-DNP dintropropane, and 2,2-DNP confirm previous findings that at constant preshock temperature the shock pressure required to produce a specific reaction time is greater when there is no hydrogen-atom alpha to the nitro group and when an additional methylene group is present. The largest contribution to the variation of failure diameter with initial temperature is the variation in smooth-shock reaction time.
