RELATIONSHIP BETWEEN DECOMPOSITION KINETICS AND SENSITIVITY

Abstract

The following studies are being carried out on the isomers, 1,2- bis(difluoroamino)propane and 2,2-bis(difluoroamino)propane, in order to assess the importance of structural variation. (1) Detonation characteristics, including shock sensitivity of the liquid phase, (2) adiabatic self-heating of the liquid phase, and (3) mecha nism and kinetics of thermal decomposition of the liquid phase. The experiments establish that both 1,2- and 2,2-DP detonate at velocities of 5-7 mm/microsec and have failure diameters of less than 10 mm. The thermal decomposition of 1,2-DP was examined in nitrobenzene solution over the range 176-187 degrees. The initial rate was found to be invariant, within experimental error, over a fourfold change in concentration (0.52-0.-14 M). After one quarter to one half life, the rate markedly accelerates vapor phase decomposition of 2,2-DP at 200 C at 0.001 mole concentration was found to be autocatalytic.
