Method for removing impurities from dinitrotoluenes |
| abstract |
The present invention relates to a process for purifying crude dinitrrotoluene resulting from the dinitration of toluene in the presence of a nitric / sulfuric acid / nitric acid mixture and an apparatus or facility for carrying out the process and to a process for the production of dinitrotoluene (A) the crude dinitrotoluene is first washed with at least one washing medium after separation of the nitric acid mixture, then the washing medium is separated; (b) then the washed dinitrotoluene resulting from process step (a) is characterized by passing through stripping (stripping gas treatment) with at least one gas (stripping gas). |
