A method for the catalytic reduction of nitrobenzene to aniline in the liquid phase
The method of the catalytic reduction of nitrobenzene to aniline in the liquid phase, where the hydrogenation is conducted in two reaction zones, where the first zone operates at the temperatures from 150°C to 250°C and the nitrobenzene concentration is kept within the range from 0.05% to 0.5% and t...

| Zusammenfassung: | The method of the catalytic reduction of nitrobenzene to aniline in the liquid phase, where the hydrogenation is conducted in two reaction zones, where the first zone operates at the temperatures from 150°C to 250°C and the nitrobenzene concentration is kept within the range from 0.05% to 0.5% and the mixture from the first zone is hydrogenated in the second zone at 50°C to 100°C to the residual nitrobenzene concentration of maximally 10 ppm. |
