The invention relates to a new method for synthesizing 4,4',5,5'-tetranitro-2,2'-biimidazole in the field of energetic materials. In this method, 2,2'-biimidazole is used as the starting material, and the target product 4,4',5,5'-tetranitro-2,2'-biimidazole is synthesized in one step through mixed acid nitration, and the yield is about 50%. Compared with the prior art, the reaction temperature of the present invention is greatly reduced, the reaction process is relatively mild, and the reaction time is greatly shortened. It is a simple and efficient 4,4',5,5'-tetranitro-2,2 A new method for the synthesis of '-biimidazole. |
