Method for synthesizing BTAHNAB by taking 3, 5-dichloroaniline as raw material

The invention belongs to the technical field of organic energetic materials and preparation thereof, and provides a method for synthesizing a novel heat-resistant energetic material 3, 3 ', 5, 5'-tetraamino-2, 2 ', 4, 4', 6, 6 '-hexanitroazobenzene (BTAHNAB) by taking 3, 5-dichloroaniline as a raw material. The method comprises the following steps: adding 3. 5-dichloroaniline into a nitro-sulfur mixed acid, and reacting to obtain 3, 3', 5, 5 '-tetrachloro-2, 2', 4, 4 ', 6, 6'-hexanitroazobenzene; then mixing with methylbenzene, introducing ammonia gas at a constant speed, stopping introducingthe ammonia gas after reaction, and continuously reacting to obtain the BTAHNAB. The preparation process is safe and simple, the preparation period is short, the preparation steps are few, and the preparation yield is high. Through calculation and test analysis, the detonation velocity of the BTAHNAB exceeds 8000m/s, the melting point of the BTAHNAB is greater than 330 DEG C, and the thermal decomposition temperature of the BTAHNAB is close to 400 DEG C, so that the obtained product has good stability and thermal stability, and is a novel heat-resistant explosive with a wide application prospect.

Method for synthesizing BTAHNAB by taking 3, 5-dichlorobenzoic acid as raw material

The invention belongs to the technical field of organic energetic materials and preparation methods thereof, and provides a method for synthesizing a novel heat-resistant energetic material BTAHNAB bytaking 3, 5-dichlorobenzoic acid as a raw material. The method comprises the following steps of: adding 3, 5-dichlorobenzoic acid into nitro-sulfuric acid, and carrying out reaction to obtain 3, 5-dichloro-4-nitrobenzoic acid; adding the 3, 5-dichloro-4-nitrobenzoic acid into sulfuric acid, dropwise adding chloroform, adding sodium azide, and carrying out reaction to obtain 3, 5-dichloro-4-nitroaniline; sequentially adding sodium nitrate and 3, 5-dichloro-4-nitroaniline into sulfuric acid, and carrying out reaction to obtain 3, 3', 5, 5'-tetrachloro-2, 2', 4, 4', 6, 6'-hexanitroazobenzene; performing mixing with toluene, introducing ammonia gas at a constant speed, stopping introducing the ammonia gas at the end of the reaction, and continuously carrying out reaction to obtain the BTAHNAB. Through calculation and test analysis, the detonation velocity of the final product exceeds 8000m/s, the melting point is larger than 330DEG C, the thermal decomposition temperature is close to 400DEG C, and the final product has good stability and thermal stability, and is a novel heat-resistant explosive with wide application prospects.
