Process for preparing aromatic amines by hydrogenation in gaseous phase and a catalyst for making the same |
| abstract |
The invented preparation process consists in catalytic hydrogenation of nitroaromatics with nitrogen on a fixedly arranged catalyst in a gaseous phase, whereby as a catalyst there is employed palladium and lead on graphite or graphite containing coke as a carrier having BET surface ranging from 0.2 to 10 square meters/g, whereby the palladium amount in the catalyst ranges between 0.001 to 7 percent by weight based on the catalyst total weight and the lead amount ranges between 0.1 to 50 percent by weight, whereby for one equivalent of nitro groups 30 to 6000 equivalents of hydrogen are supplied to the catalyst. |
