Sensitivity Fundamentals
Abstract
The report summarizes research on the relationship between detonation phenomena, chemical structure, and kinetics for isomeric dinitropropanes and other nitroalkanes. Research on dinitropropanes was carried out in three areas: high velocity detonation (HVD), low velocity detonation (LVD), and static high pressure and kinetic effects. An alpha-hydrogen effect on reaction times was found for 1,1-DNP(dinitropropane) and 2,2-DNP at 60C: and 1,1-DNE and 1,1,1- FDNP(fluorodinitropropane) at 25C. The isomers methyl nitrite and nitromethane have similar reaction times at shock pressures of 57 and 79 kbar respectively. Reaction time measurements at 10kbar for several dinitroalkanes give a shorter time for 1,1-DNP than for 2,2-DNP or 1,1,1-FDNP with marked change in reaction time with temperature for 1,1,1-FDNP. Products studies for very low pressure pyrolysis of four dinitroalkanes give the 1,2-DNP, 1,1-, and 2,2-DNP, and 1,1,1- FDNP decomposition mechanisms.
