    摘要:

    采用溶剂-非溶剂重结晶技术制备了类球形和立方体结构两种不同晶形的细颗粒2,6-二氨基-3,5-二硝基吡嗪-1-氧化物(LLM-105),重均平均粒径D50分别为2.750 μm和6.206 μm,撞击感度为35.5 cm和 34.7 cm。采用热重-微商热重(TG-DTG)和差示扫描量热法(DSC)对LLM-105进行了热分析,根据Kissinger方程计算了LLM-105的热分解动力学参数,其热分解活化能为257.55 kJ·mol-1,指前因子为3.3×1019s-1,线性相关系数为0.9930。

    Abstract:

    Two kinds of resemble sphere and cubic crystals of 2,6-diamino-3,5-dinitropyrazine-1-oxide(LLM-105) were prepared using solvent-nonsolvent recrystallization technology. The average particle (D50) is 2.750 μm and 6.206 μm,impact sensitivity(H50) is 35.5 cm and 34.7 cm,respectively. Thermal properties of LLM-105 were analyzed with thermogravimetry-derivative thermogravimetry(TG-DTG) and differential scanning calorimetry(DSC). Thermal decomposition kinetics parameters of LLM-105 were obtained by Kissinger equation. The value of activation energy,pre-exponential factor and linear correlation coefficient is 257.55 kJ·mol-1,3.3×1019 s-1 and 0.9930,respectively.
