Effect of malonyl malonanilide dimmers on the thermal stability of nitrocellulose

摘要

There malonanilide dimmers (MA2-MA4) were prepared by the reaction of ethyl malonate with malonanilide derivatives (M2-M4). These dimmers were investigated as new stabilizers for nitro- cellulose. The evaluation process has been performed through Bergman-Junk (BJ) test, thermal analysis measurements (TGA and DSC) and kinetic parameters calculations (E_a). The comparative study between mass spectra and thermal analysis of the new dimmers helped in resolving the thermal decomposition mechanisms for the new dimmers.
