Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Nitric Acid | HCID 944 | — |
| Reactant | Sulfuric Acid | HCID 1118 | — |
| Reactant | 2,3-Dinitrotoluene | HCID 11761 | — |

Reaction Steps
The process according to the invention is preferably used for the production of dinitrotoluene by the two-stage reaction of toluene with nitric acid in the presence of sulphuric acid, wherein in the first stage toluene is nitrated to form mononitrotoluene (MNT) using waste acids from the second stage, in which mononitrotoluene is nitrated to form dinitrotoluene (DNT) using concentrated waste acid from the first stage.
