A new explosive 1,1-dinitro-2,2-di(2,4,6-trinitrobenzoyl amino)ethylene 3 was synthesized by the reaction of 1,1-diamino-2,2-dinitroethylene (FOX-7) with 2,4,6-trinitrobenzoyl chloride (TNBC). The product was characterized by UV-Vis, ¹H NMR, ¹³C NMR, FT-IR and MS techniques. The reaction conditions affecting the yields of product were investigated, and the optimum reaction conditions with 94% yield are 1∶2.4 molar ratio of FOX-7 and TNBC, reaction temperature 0 ℃ and reaction time 48 h. The thermal stability of product 3 was studied by differential thermal analysis (DTA). DTA curve showed that the peak temperature of decomposition was 167 ℃ in the atmosphere. The theoretical detonation velocity is 7.434 km•s^－1, and the theoretical detonation pressure is 23.67 GPa.

Key words: 1,1-diamino-2,2-dinitroethylene (FOX-7), 2,4,6-trinitrobenzoyl chloride (TNBC), synthetic technology, thermal stability, energetic material
