Abstract:

The report summarizes a six-month period of research on the relationship between detonation phenomena, chemical structure, and kinetics for isomeric dinitropropanes and other nitroalkanes, sponsored by the Office of Naval Research. Research on dinitripropanes is being carried out in three AREAS high velocity detonation HVD, low velocity detonation LVD, and kinetics of thermal decomposition. Shock temperature calculations were made for seven nitroalkanes and nitrate esters over a range of 0 to 200 kbars. Smooth shock reaction times, measured at ambient temperatures and pressures, indicated that 1,1-dinitroethane 1,1-DNE initiates faster than 1,1-dinitropropane 1,1-DNP methyl nitrite did not initiate at 45 kbar. Energy release under LVD conditions was calculated for ethyl nitrate, 1,1-DNP, nitromethane and 1,1-DNE using TIGER code. Kinetic parameters for five nitro and dinitropropanes were measured in a modified VLPP apparatus.
