摘要

The easily decomposable nature of nitrate esters makes stabilizers essential component for the storage and application of nitrate ester-based energetic formulations. The understandings of compatibilities and interaction mechanisms between stabilizers and nitrate esters are of vital importance for the development of propellant or explosive formulations containing nitrate esters. In this article, a comparative study was conducted between the thermal decomposition processes of DNTN and DINA, two high energetic nitrate esters with similar branched structures, as well as their respective mixed system with stabilizing agent of C2. The addition of C2 significantly advanced the thermal decomposition temperature of DNTN, while having almost no effect on the thermal decomposition of DINA. The thermal decomposition kinetics of DNTN showed a significant change in activation energy after the addition of C2 compared to non-C2 one, indicating a clear interaction between DNTN and C2 which makes C2 not suitable be used as a stabilizer for DNTN. The results of in situ infrared experiments and DSC/TG-FTIR-MS combined experiments indicate that C2 may promote the release of NO in DNTN, thereby promoting the thermal decomposition process of DNTN.
