Method for removing impurities from dinitrotoluenes |
| abstract |
The present invention relates to a method for purifying raw dinitrotoluenes resulting from dinitration of toluene in the presence of a nitric acid/sulfuric acid/nitrating acid mixture, and a device or plant for performing the method, and a corresponding production plant for producing dintrotoluene, characterized in that (a) the raw dinitrotoluenes are first subjected to a wash with at least one washing medium after separation of the nitrating acid mixture, followed by a separation of the washing medium; and that (b) subsequently the washed dintrotoluenes resulting from method step (a) are subjected to stripping (stripping gas treatment) with at least one gas (stripping gas). |
