The thermal decomposition process of 2,6-hexanitrodiphenyl-amine-3,5-dinitropyridine(PYX) was investigated by TG/DTG,TG/FTIR,TG/MS and therolysis rapid scan FTIR coupling techniques.

• 用热重-微商热重分析(TG/DTG)、热重与傅里叶变换红外联用技术(TG/FITR)、热重与质谱联用(TG/MS)和热裂解快速扫描傅里叶变换红外技术(RSC/FTIR)研究了PYX(2,6-二苦氨基-3,5-二硝基吡啶)热分解过程。
