Differential scanning calorimetry (DSC) provides a convenient technique for monitoring the global reactivity in real time for decomposition of a variety of secondary explosives. Thermograms for decomposition of explosives are frequently characterized by nonzero initial rates followed by additional transitions involving autocatalysis. An example of this phenomenon is illustrated for decomposition of 2,2',4,4',6,6'-hexanitroazobenzene (HNAB) at temperatures of 590 and 600K. Thermograms exhibit nonzero initial rates followed by autocatalytic transitions exhibiting maxima in the range of 250--500 s. In view of the complexity and frequency of occurrence of these types of thermograms, a computer program was devised to evaluate global rate parameters using nonlinear regression. 7 refs., 5 figs., 1 tab.
