Method for producing aromatic amine |
| abstract |
The present inventionn n n a) reacting the aromatic hydrocarbon (s) with a mixture of nitric acid and sulfuric acid to produce a two-phase reaction mixture;n n n b) the reaction mixture is separated into an aqueous acid phase and an organic phase containing nitroaromatic compounds;n n n c) washing the organic phase to purify the nitroaromatic compound (s);n n n d) hydrogenating the nitroaromatic compound (s) in the presence of a catalyst to produce aromatic amine (s) and reaction water;n n n e) separating the reaction water formed in step d) from the aromatic amine (s)n n n To a process for producing an aromatic amine from an aromatic hydrocarbon, wherein the reaction water separated in step e) is used to wash the organic phase containing the nitroaromatic compound in step c). n n n Nitroaromatic compounds, reaction water, aromatic amines, production methods |
