含微量杂质的苯并三氧化呋咱安定性能研究

Study on the Stability of Benzotrifuroxan with Trace Impurities

以苯并三氧化呋咱(BTF)及混有不同微量三叠氮三硝基苯(TATNB)、三氯三硝基苯(TCTNB)和叠氮化钠(NaN3)等杂质的BTF混合物作为研究对象,分别采用热重 红外(TG IR)联机技术、加速量热仪(ARC)、5s爆发点实验和撞击感度实验等分析方法,研究了BTF及其混合物的安定性能,进一步探讨和评价了各种微量杂质对BTF安定性的影响。

Benzotrifuroxan, mixtures with TATNB, TCTNB or NaN3 were selected as the target to study their stability by TGIR, ARC, 5second delay explosion test and impact sensitivity test. The effect of above impurities in BTF on its stability were evaluated and discussed. These impurities made the decomposition peak temperature move to lower direction. NaN3 increased the thermal sensitivity of BTF, whereas TATNB enhanced the mechanic sensitivity.
