| titleOfInvention | Preparation method of insensitive explosive TATB |
| abstract | The invention provides a preparation method of a insensitive explosive TATB. The method comprises the following steps: step 1: 2,4, 6-trinitrotoluene is taken as a raw material and reacts with hydrogen and acetic anhydride in sequence to obtain 2,4, 6-triacetyl amino toluene; step 2: carrying out oxidation and decarboxylation reactions on the obtained 2,4, 6-triacetyl amino toluene to obtain 1,3, 5-triacetyl amino benzene; and step 3: carrying out nitration and hydrolysis reaction on the obtained 1,3, 5-triacetyl aminobenzene to obtain 2,4, 6-trinitro-1, 3, 5-triaminobenzene. The raw materials adopted in the preparation method are low-price 2,4, 6-trinitrotoluene, and the used reactants or catalysts are common products in the chemical industry, so the preparation method has the characteristics of low cost and simple and easily obtained raw materials. In addition, the preparation method has the characteristics of short synthesis steps, simple operation of each step, high yield, high reaction rate, easy separation and collection of intermediate and final products and the like, and is favorable for realizing the mass production of TATB. |
