    摘要:

    以2, 4, 6-三硝基氯苯, 1, 1-二氨基-2, 2-二硝基乙烯(FOX-7)为原料, 咪唑与氟化钾作为催化剂, 缩合合成了1, 1-二苦氨基-2, 2-二硝基乙烯(TFT), 熔点为225~226 ℃, 收率71.3%。采用红外光谱、核磁共振、质谱对其进行了表征。通过差示扫描量热研究了其热性能, 热分解温度为331.3 ℃, 热稳定性优于FOX-7。用Monte-Carlo方法估算其理论密度为1.85 g·cm-3, 用Kamlet-Jacobs公式估算其爆热为1751.26 J·g-1, 爆速为8.83 km·s-1, 爆压为36.25 GPa; 撞击感度H50的计算值为156 cm。理论计算的结果说明该材料较FOX-7钝感, 爆压高于FOX-7。

    Abstract:

    1, 1-Bis(picrylamino)-2, 2-dinitroethylene (TFT) was synthesized using 2, 4, 6-trinitrochlorobenzene and 1, 1-diamino-2, 2-dinitroethylene (FOX-7) as raw materials and KF and imidazole as catalysts by condensation with the yield of 71.3% and melting point of 225-226 ℃. Its structure was identified by IR, NMR and MS. Its thermal stability was analyzed by DSC and the decomposition temperature was 331.3 ℃, which indicating that its thermal stability was better than that of FOX-7. The theoretical density of TFT after optimizing predicted by Monte-Carlo method is 1.85 g·cm-3. The heat of detonation, detonation velocity and detonation pressure predicted by Kamlet-Jacobs formula are 1751.26 J·g-1, 8.83 km·s-1 and 36.25 GPa, respectively. Impact sensitivity(H50) is 156 cm. All the results show that TFT is more insensitive and has higher detonation pressure than FOX-7.
