| titleOfInvention | Method for production of dinitrotoluenes and product being prepared by this method |
| abstract | This invention describes a toluene nitration method for producing dinitrotoluene, characterized by a liquid-phase nitration reaction, characterized in that it is a reaction of anhydrous nitric acid with toluene in a reactor at a reaction temperature of between 20 and 30 ° C. for a reaction time of less than 15 minutes with a molar ratio of nitric acid plus water to toluene between 10: 1 and 15: 1, the above reaction being carried out in the absence of sulfuric acid and any aprotic dipolar solvent during the reaction and in the absence of any aprotic dipole a solvent to stop the reaction to obtain the above dinitrotoluene in a mixture of products without nitrocresol impurity, followed by distillation in a vacuum of a mixture of products without using any aprotic dipolar solvent to remove unreacted nitric acid from the above mixture of products, thereby obtaining the above dinitrotoluene. |
