Process for the preparation of toluenediamine by catalytic hydrogenation of dinitrotoluene |
| abstract |
The present invention relates to a process for producing toluenediamine in which dinitrotoluene is reacted with hydrogen in the presence of a catalyst. The dinitrotoluene required for this method has a carbon dioxide content of 0.175 mol% or less based on the molar amount of dinitrotoluene in physically dissolved form or in chemically bound form. |
