我们曾发现,重(三硝基乙基)乙二硝胺(BTNE)晶体热分解反应速度常数k的数值与该晶体重结晶条件有关系,而不同重结晶过程有可能给出性质各异的品体。在本文中,作者们利用差示扫描量热(DSC)、X-光多晶衍射、电子扫描显微镜(SEM)技术研究了工作[1]中提到的十种BTNE晶体,BTNE的单晶(BT-M)和未经任何重结品处理的实验室合成的BTNE粗品(BT-U)的晶体性质。利用DSC和X-光多晶衍射技术研究了BTNE晶体的晶型。同一晶体的不同晶型具有各自的X-光衍射图,而不同晶型间的转换可在DSC曲线上表现出存在有相应的吸热峰。工作[1]中给出的DSC曲线表明,
We have found that the numerical value of the thermal decomposition reaction rate constant k for heavy (trinitroethyl) ethylenediamine (BTNE) crystals is related to the recrystallization conditions of the crystal, and different recrystallization processes may give different properties Body. In this paper, the authors studied ten BTNE crystals mentioned in [1], single crystal of BTNE (single crystal of BTNE) BT-M) and laboratory-synthesized BTNE crude (BT-U) without any recrystallization. The crystalline forms of BTNE crystals were investigated by DSC and X-ray polycrystal diffraction. Different crystalline forms of the same crystal have their own X-ray diffraction patterns, whereas the transitions between the different crystalline forms show the presence of a corresponding endothermic peak on the DSC curve. The DSC curve given in working [1]
