2,4-Dinitrophenyl and Pentaerythrityltrinitrate as Explosophoric Units in the Synthesis of New Energetic Materials

In memory of Professor Edward Piers

Abstract

Three novel energetic compounds were prepared from the common precursor 1-fluoro-2,4-dinitrobenzene by using nucleophilic aromatic substitution as a key step with pentaerythritol, pentaerythritoltrinitrate, or glycidol. The thermal stability of 3-(2,4-dinitrophen­oxy)-2,2-bis[(nitrooxy)methyl]propyl nitrate was assessed by differential scanning calorimetry and its X-ray structure was determined. In light of the success in using 2,4-dinitroanisole as an additive in explosive formulations, some of the analogous compounds prepared in the present study may be considered as suitable materials for diverse composite energetic material formulations.

Key words

synthesis - energetic materials - explosophoric unit - aromatic nucleophilic substitution - detonation velocity - impact sensitivity
