| titleOfInvention | Method for preparing low-sensitivity high-energy explosive 1-amino-2,4-dinitroimidazole |
| abstract | The invention discloses a method for preparing a low-sensitivity high-energy explosive 1-amino-2,4-dinitroimidazole. The method comprises the steps of firstly, preparing 2,4-dinitroimidazole potassium salt from 2,4-dinitroimidazole and solid KOH at room temperature, then, preparing a mixture of 1-amino-2,4-dinitroimidazole and trimethyl potassium benzenesulfonate from the 2,4-dinitroimidazole potassium salt and 2,4,6-trimethyl benzenesulfonyl hydroxylamine, and washing with ethyl acetate to purify, thereby obtaining a target product. According to the method, an organic toxic reagent, namely methanol, in the prior art is replaced with water, and the reaction temperature is low, so that the operating process is safer; the reaction temperature of the method is room temperature and has no need of being reduced to the temperature of 0 DEG C, and the reaction time of the method is greatly shortened to 4-5 hours, so that the operation is easier, and the efficiency is higher; in a purifying step of the method, ethyl acetate is directly used for washing, a crude target product ADNI, of which the purity reaches up to 96%, can be obtained in a manner that a filtrate resulting from filtrating is subjected to depressurized concentration and then subjected to oscillating dilution with water directly, and the purity can reach up to 99.6% after the crude target product ADNI is re-crystallized with anhydrous ethanol. |
