DATB,TATB和其中间体的新合成法

A NEW METHOD FOR THE PREPARATION OF DATB,TATB AND THEIR INTERMEDIATES

间硝基苯甲酸(la)和3,5-二硝基苯甲酸(1b)在超酸介质中与叠氮化钠作用,分别生成间硝基苯胺(2a)和3,5-二硝基苯胺(2b)。利用2a和2b的进一步反应,得到1,3-二氨基-2,4,6-三硝基苯(DATB)和1,3,5-三氨基-2,4,6-三硝基苯(TATB)。这是一种合成耐热炸药DATB和TATB的新途径。

Treating m-nitrobenzoic acid (la) and 3, 5-dinitrobenzoic acid (1b) with sodium azide in super-acid medium gave m-nitroaniline (2a) and 3, 5-dinitroaniline (2b), respectively. 1, 3-diarnino-2, 4, 6-trinitrobenzene (DATB) and 1, 3, 5-triamino-2, 4, 6-trinitrobenzene (TATB) were then obtained via further reactions of the intermediates, 2a and 2b. This represents a new route for the preparation of heat-resistant explosives, DATB and TATB.
