用裂解气相色谱鉴定十三种炸药

IDENTIFICATION OF THIRTEEN KINDS OF EXPLOSIVES BY PGC

本文用裂解气相色谱(PGC)分析了季戊四醇四硝酸酯(PETN)、纤维素硝酸酯(NC)、硝化二乙醇胺(GINA)、环四亚甲基四硝胺(HMX)、环三亚甲基三硝胺(RDX)、2,4,6-三硝基苯甲硝胺(Te)、2,4,6-三硝基甲苯(TNT)、二硝基甲苯(DNT)、2,4,6-三硝基苯胺(TNA)、过氯酸铵(AP)、2,4,6-三硝基-2,4,6-三氮杂环已酮(TCH)、1.3,3,5,7,7-六硝基-1,5-二氮杂环辛烷(HCO)和四氮烯起爆药(TTZ)等十三种炸药。得到了完全可以互相区别的指纹图,考察了实验的重复性,讨论了裂解温度选择以及PGC用于炸药热感度和热分解研究的可能性。结果表明,PGC用于火炸药的分析和研究是很有意义的。

Pyrolysis-Gas Chromatography(PGC or PyGC)is not only an important method for the study of a variety of polymers, but also a rapid and simple means for the identification of many organic compouds, In this paper, PGC is used for the identification of explosives, including PETN, NC, GINA, HMX, RDX, Te, TNT, DNT, TNA, AP, TCH, HCO and TTZ. Results are seem to be satisfactory. The distinguised fingerprint pyrogram for each sample has been obtained, and experimental reproducibility has been investigated. Selection of pyrolysis temperature, possibility of studying heat sensitivity and thermal decomposition of explosives by PGC are also discussed,
