THERMAL-DECOMPOSITION OF TETRAZOLE .2. KINETIC-ANALYSIS

This article elucidates the kinetic scheme of the process of tetrazole thermolysis and ascertains the results of the kinetic investigations described in Part I (Thermochim. Acta, 145 (1989) 195). Based on the processing of a series of DSC curves, an overall scheme for tetrazole thermolysis is proposed which represents two parallel processes, one of which proceeds through a reversible endothermal stage. A physical interpretation of this scheme and evaluation of the parameters of some of the stages are given. The scheme in question explains the unusual character of the heat release (a narrow endo effect against the background of a wide exo effect) as a result of the superposition of the endo- and exothermal processes forming it. © 1990.
