摘　　要：为寻求可替代梯恩梯用于熔铸炸药的液相载体,研究绘制了1,3,3-三硝基氮杂环丁烷(TNAZ)与3-氨基-2,4,6-三硝基苯甲醚(ANTA)混合物的二元相图,并测定了最低共熔物的感度、热安定性、爆轰性能。结果表明,当TNAZ与ANTA质量比为60/40时为最低共熔物,共熔点为84℃;最低共熔物热分解温度高、热安定性好、撞击感度、摩擦感度和静电火花感度与TNT相当,做功能力相当于148%TNT和114% Comp.B;70℃恒温放置6h不渗油,是一种具有潜力的可替代TNT的熔铸炸药。A phase diagram of 1,3,3-trinitroazetidine（TNAZ） and 3-amino-2,4,6-trinitroanisole （ANTA） was draw by origin software and the sensitivity, thermal stability, and detonation performance of the eutectic mixture were tested in order to design a potential TNT replacement for melt-cast explosive. The results show that when the weight percent of 3-methoxy-2,4,6-trinitrobenzenamine is 40%, the mixture has the lowest melting point, 84 ℃. The eutectic mixture has good thermal stability and its friction sensitivity, impact sensitivity, electrostatics sensitivity are comparable to TNT. The working capability of the mixture is 148% equivalent to TNT and 114% equivalent to Comp.B. Furthermore, another advantage of eutectic mixture is that there is no permeability oil at 70 ℃ for 6 h. These results indicate that the eutectic mixture is a potential replacement of TNT for melt-cast explosive.
