| titleOfInvention |
Process for preparing aromatic amines or aliphatic amino alcohols |
| abstract |
The present invention is a process for producing aromatic amines by hydrogenation of nitroaromatic compounds in the presence of a catalyst, which comprises forming a fluid amine containing reaction mixture in the reactor and separating and removing the catalyst from the reaction mixture. After the catalyst is separated off, the method of the present invention consists in measuring the UV / VIS radiation absorbance by the reaction mixture to determine the concentration of nitro and nitroso compounds in the reaction mixture. |
