| titleOfInvention | A process for preparing dinitrotoluene |
| abstract | Described herein is a continuous one pot process for the production of dinitrotoluene by: a) reacting toluene with concentrated nitric acid to produce a product mixture containing dinitrotoluene, unreacted nitric acid and water; b) then mixing the product mixture from step (a) with a substantially dehydrated molten nitrate salt; c) then adding additional nitric acid to the mixture of step (b); d) then separating nitric acid from the mixture from step c) in the form of a vapor to form a two phase liquid mixture; e) then separating the dinitrotoluene phase from the liquid hydrated salt phase; f) then treating the acid vapor from step d) and the hydrated salt-liquid phase of step (e) to separate and concentrate nitric acid for recycle to step (a); g) dehydrating the nitrate salt solution; and h) recycling the dehydrated nitrate salt to step (b). |
