Embodiment Construction
[0007] TNT can be produced with two kinds of raw materials, and its technology is different, and the specific implementation mode is described as follows:
[0008] A. Refining of TNT production with toluene as raw material: crude TNT contains 4.5% asymmetric TNT, about 0.5% DNT (dinitrotoluene), a small amount of trinitrobenzoic acid, trinitrobenzyl alcohol, tetranitrotoluene methyl methane, and the nitrated derivatives of impurities in toluene such as benzene, ethylbenzene, and xylene. There are more than 20 kinds of impurities in total. The refining method is: 1. Add 90-97% of industrial SA into the crystallizer, and control the temperature Stir 60 times / min at 100-120°C, then add the crude TNT separated by pre-washing, the ratio of SA to TNT is 3-3.5:1 (V / V), so that they are completely miscible. 2. When the temperature is gradually lowered to 70-80°C, add a little pure TNT seed crystal to crystallize. 3. When the temperature drops to 20-40°C, put it into a filter for vacu...
