Abstract

The relationship between the critical temperature of spontaneous ignition, calculated using the maximum heat of explosion and the kinetic parameters (activation energy and pre-exponential factor) of the decomposition reaction in the liquid phase, and the sensitivity index h50 is analyzed for a set of substances representing all major classes of explosive compounds. It is demonstrated that the derived correlation equation can be used to predict the sensitivity of new compounds. The relationship between the sensitivity of the compounds and their molecular structure is also analyzed.
