| titleOfInvention | Process for producing aromatic amines by gas-phase hydrogenation |
| abstract | SUMMARY OF THE INVENTION The present invention relates to a ceramic support material having a BET surface area of less than 40 m 2 / g, comprising a member of Group VIIIa, Ib, Ilb, IVa, Va, VIa, IVb and Vb of the Periodic Table of the Elements (Mendeleev). The corresponding aromatic nitro compound in the gas phase is immobilized on a fixed catalyst containing one or more metals at a molar ratio of hydrogen to nitro groups of 3: 1 to 30: 1 and a catalyst bed of 180 to 500 ° C. The present invention relates to a process for producing an aromatic amine by catalytic hydrogenation at a temperature, wherein the amount of the catalyst to the aromatic nitro compound used is continuously or stepwise adjusted to 0.01 to 0.5 kg / l. × h to 0.7 to 5.0 kg / l × h to reach the maximum filling amount within 10 to 1000 hours. The process according to the invention can be carried out without problems on an industrial scale and high space-time yields can be realized in combination with the increased productivity of the catalyst used. |
