Abstract
For a set of substances representing all the main classes of explosive compounds, the relationship between the critical autoignition temperature calculated using the maximum heat of explosion and kinetic parameters (activation energy and pre-exponential factor) of the decomposition reaction in the liquid phase, and the sensitivity index h50 was analyzed. The found correlation equation can be used to predict the sensitivity of new compounds. The relationship between the sensitivity of compounds and their structure was analyzed.
