首发时间:2011-04-12
摘要:本文报道了二苦胺含能离子盐的合成,采用NMR谱,IR和EA对它们的结构进行了鉴定,对离子盐4和6进行了单晶X射线衍射表征。该类含能离子盐表现出了较好的物理性质,如较高的密度(1.71-1.78gocm-3)和较好的热稳定性(Td=185-285℃)。结合实测密度和用等键反应计算的生成焓基于Kamlet-Jacobs方程计算了含能离子盐的爆速和爆压,爆速介于7241mos-1和7865mos-1之间,爆压介于22.6GPa和27.3GPa之间,均优于梯恩梯(TNT)。

Synthesis and Properties of Dipicrylamine-Based Energetic Salts
Abstract:Energetic salts of the dipicrylamine anion paired with different organic cations were synthesized. All salts were fully characterized by multinuclear NMR spectroscopy, vibrational spectroscopy (IR) and elemental analysis. Salts 4 and 6 were further confirmed by single crystal X-ray diffraction. These salts exhibit reasonable physical properties, such as high densities (1.71-1.78gocm-3), good thermal stability (Td=185-285℃). Based on experimental densities, and theoretical calculations carried out by using Gaussian 03 suite of programs, all the salts have calculated detonation pressures (7241-7865mos-1)and velocities (22.6 -27.3GPa) that exceed those of conventional 2,4,6-trinitrotoluene (TNT).
Keywords: Applied chemistry Dipicrylamine Energetic salt TNT replacement
