Abstract : 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 kinetics of thermal decomposition. Densities, sound speeds, and heat capacities have been measured for several dinitroalkanes. Group additivity values developed from these measurements were used to calculate values of C(p) for several additional dinitroalkanes. LVD gap sensitivity measurements on 2,2-dinitropropane and 1,1-dinitroethane showed that the former did not and the latter did undergo LVD. HVD sensitivities measured for nitromethane, 2,2-dinitropropane, 1,1-dinitroethane, and 1,1-dinitropropane increased with temperature and with decreasing charge diameters. LVD sensitivity seemed to increase with an increase in the oxygen balance; compounds producing free carbon. (Author)
