| titleOfInvention | Process for adiabatic production of mononitrotoluene |
| abstract | A process for continuous adiabatic nitration of toluene to mononitrotoluene (MNT). The process yields a product quality of MNT that is comparable to that obtained by isothermal production. The process uses excess toluene, with the reaction rate being controlled to maintain a residual of 0.003-0.102 wt % nitric acid in the spent acid and an orange to red color of the spent acid. Further process conditions include re-concentrated sulfuric acid at 83 to 99 degrees C. with a concentration of sulfuric acid from 66 to 70.5 wt %. This is mixed with nitric acid to generate a mixed acid with 1.0 to 3.8 wt % nitric acid and toluene is added at a rate of 1.1 to 1.71 moles toluene/mole nitric acid. The reactants are mixed in a reactor with an overall average mixing intensity of 5.8 to 19 W/kg of contained solution. |
