The aim of these works consisted in the development and evaluation of quantitative structure property models (QSPR) for the prediction of explosive properties of nitroaromatic compounds, to be used within a regulatory context, in particular the new European regulation called REACH. Different methodological approaches (multilinear regressions, PCA, PLS, decision trees) were used to develop models for the prediction of the heat of decomposition. The descriptors of the model are selected among an extended set of more than 300 (constitutional, topological, geometric and quantum chemical) descriptors. Applicability domains were defined and the predictive power was determined using a set of validation. Three other properties (decomposition temper...
