Though related to CL-20 in that is shares the same cage structure TEX is more easily synthesized in good yield from cheap starting materials.〔A. T. Nielsen Polycyclic Amine Chemistry, in G. A. Olah, D. R. Squire, ''Chemistry of Energetic Materials'' (Eds.) Academic Press, 1991, p. 110-111〕 Much unlike CL-20 TEX is friction insensitive, bears a low impact sensitivity and possesses a very low shock sensitivity and large critical diameter making it an interesting explosive filler for insensitive munitions. Its systematic name, 4,10-Dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo()-dodecane derives from its tetracyclic structure which is depicted below. ==Synthesis and Production== Unlike CL-20, which requires a cumbersome and even costly procedure, TEX is obtained in moderate yield (40 wt.-%) in a one-pot synthesis from 1,4-diformyl-2,3,5,6-tetrahydroxypiperazine (DFTHP) and mixed acid (H2SO4/HNO3). The DFTHP thereby partly undergoes proton-catalyzed hydrolysis and yields glyoxal which reacts as with an intermediate to give TEX as is depicted in the scheme 1.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「TEX-explosive」の詳細全文を読む スポンサード リンク
