KINETICS OF DECOMPOSITION OF SOLID OXIDIZERS.
Abstract
The thermal decomposition of PFABDE and PBEP is being studied using a mass spectrometer technique providing high time resolution. Sample heating rates are employed that simulate conditions prevailing during explosive material decomposition or propellant combustion, using cinematographic techniques to record the oscilloscope output. With both materials, thermal decomposition was found to initiate at relatively low temperatures with rapid increases in decomposition rates thereafter. Initial pyrolysis species were identified, and decomposition mechanism were established. In both cases more than one mechanism is at play, and the data suggest that PBEP thermal stability in particular may be adversely affected by structural nonuniformity. The method now used provides a relatively easy means of estimating activation energies for the various processes, and pertinent data will be obtained to arrive at comparative shelflife predictions.
