Process for the preparation of dinitrotoluene |
| abstract |
The invention relates to a two-stage process for the production of dinitrotoluene from toluene and a nitrating acid, in a first stage mainly mononitrotoluene by reaction between nitric acid and toluene with a molar ratio of 0.7: 1 to 1.2: 1 in a continuously operated reactor is obtained adiabatically at a temperature between 0 and 140 ° C, and in a second stage the mononitrotoluene obtained in the first stage is reacted adiabatically with nitric acid at a temperature between 20 and 200 ° C with adjustment of the same molar ratio in a continuously operated reactor becomes. After each step, the acid is freed from at least 5% of the water by distillation and, after the addition of highly concentrated nitric acid, returned to the reaction. |
