Abstract:

Smear camera observations were made of detonation waves in nitromethane, 1,2-DP, and 2,2-DP. The nitromethane gave essentially conventional results, the detonation wave having a velocity of 6.5-6.7 mmmicrosec. Possibly the velocity was still decreasing very slowly 30 cm from the liquid-donor interface. This compares with a steady velocity of 6.3 mmmicrosec reported by earlier observers. The 1,2-DP and 2,2-DP, however, again exhibited the anomalous behavior observed in previous report periods with continuous wire and pin techniques. The detonation velocity varied from shot to shot sometimes it appeared steady, sometimes it accelerated, and sometimes it decelerated. Solutions were obtained for equations which describe a model of 3-dimensional, axially symmetric, laminar detonation waves in homogeneous condensed materials. Adiabatic self-heating runs were made on 2,2-DP and IBA. The rate of decomposition of pure 1,2-DP was measured and compared with calculated values. It has been tentatively concluded that the structure of an intermediate resulting from the decomposition of 1,2-DP is 2-N-fluoroimino propionitrile.
