7-Amino-6-nitrobenzodifuroxan (ANBDF) was synthesized from 1,3,5-trinitro- 2,4-dichlorobenzene through azidation, denitrogenation and vicarious nucleophilic substitution (VNS) reactions. ANBDF and the intermediate products were characterized by IR, NMR, MS techniques and elemental analysis. The optimal conditions of VNS were discussed and confirmed. The best conditions were obtained as follows: the VNS reagent is NH2OH•HCl, the reaction time is 5 h, the reaction temperature is 20~40 ℃, and the overall yield is 51.0%. The results show that ANBDF had favorable mechanical sensitivities and thermal stability. DSC and TG-DTG measurements indicate that there were two decomposition processes of ANBDF at 194.1 and 200.2 ℃.
