PROCESS FOR THE PRODUCTION OF DINITROTOLUOLS |
| abstract |
The present invention relates to a process for the preparation of dinitrotoluene by the reaction of mononitrotoluene and nitric acid in the liquid phase. The process is characterized in that the reaction is carried out in the presence of a metal sulfate and optionally in the presence of a dismutating agent selected from the perfluorinated (poly) cycloalkanes having from 5 to 12 carbon atoms and perfluorotoluene. {Dinitrotoluene preparation; Reactants; Mononitro Aoluol; Nitric acid; Metal sulfate; Verduennungsmittel} |
