Weak acid process for producing dinitrotoluene |
| abstract |
This invention relates to an improved process for the production ofndinitrotoluene wherein one is able to effectively employ a feed sulfuric acid, which isnreferred to as "weak acid" as the feed sulfuric acid for the nitration facility. The weaknacid concentration, as feed, ranges from 86-91%, preferably 87-89% sulfuric acid bynweight, to meet the total sulfuric acid requirements for the facility. This is accomplishednby utilizing cocurrent processing in a mononitration zone and countercurrent nitrationnwith respect to sulfuric acid in the dinitration zone. |
