Decomposition of some polynitro arenes initiated by heat and shock Part Ⅱ: Several N-(2,4,6-trinitrophenyl)-substituted amino derivatives

摘要

Samples of 2,4,6-trinitroaniline (RAM), 2,4,6-trinitro-N-(2,4,6-trinitrophenyl)aniline (DPA), N,N′-bis(2,4,6-trinitrophenyl)-3,5-dinitropyridine-2,6-diamine (PYX) and N,N′,N″-tris(2,4,6-trinitrophenyl)-1,3,5-triazine-2,4,6-triamine (TPM) were exposed to heat or to shock and then analysed chromatographically (LC-UV and LC/MS). It was found that the main identified decomposition products of these two incomplete initiations are identical for each of the compounds studied. It has been stated that the chemical micro-mechanism of the primary fragmentations of their low-temperature decomposition should be the same as in the case of their initiation by shock, including fragmentation during their detonation transformation.
