The relationship between kinetic data of the low-temperature thermolysis and the heats of explosion of organic polynitro compounds

Abstract

A linear relationship between the activation energies of the initial stage of non-autocatalysed, low-temperature thermolysis and the heats of explosion of organic polynitro compounds is presented. This was derived from discussions on a set of problems concerning the identity of primary chemical processes of the thermal decomposition and detonation of organic explosives. The necessary kinetic data of thermal decomposition for the studied compounds were taken from the results obtained by the Soviet manometric method (SMM) and the Rogers method of differential scanning calorimetry (DSC). The data obtained from differential thermal analysis (DTA), i.e., Piloyan activation energies of the initial exothermal decomposition of some of the above mentioned compounds, were used as a supplement. It is also shown that the kinetic data obtained by DTA according to Kissinger are not applicable to the study of the micromechanism of the initiation of detonation.
