RELATIONSHIP BETWEEN DECOMPOSITION KINETICS AND SENSITIVITY

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 mm/microsec. Possibly the velocity was still decreasing very slowly 30 cm from the liquid-donor interface. This compares with a steady velocity of 6.3 mm/microsec 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.
