| titleOfInvention | Process for the production of dinitrotoluene |
| abstract | The present invention uses a molar ratio of nitric acid and water to toluene in a reactor with a halftone temperature of 20 to 30 ° C. for a reaction time of less than 15 minutes in a ratio of 10: 1 to 15: 1, in the absence of sulfuric acid, and during the reaction. Reacting nitric anhydride with toluene in the absence of a bipolar aprotic solvent to provide dinitrotoluene in the product mixture free of nitrocresol, which is vacuum distilled in the absence of a bipolar aprotic solvent to the product mixture. The present invention relates to a nitration method of toluene for producing dinitrotoluene characterized by a liquid nitration reaction of nitric anhydride and toluene to remove unreacted nitric acid to provide dinitrotoluene. |
