| titleOfInvention | Process for purifying aniline from gas phase hydrogenations |
| abstract | The invention relates to a process for purifying aniline prepared by gas phase hydrogenation of nitrobenzene, by fractional condensation of the crude reaction product obtained in gaseous form so as to obtain at least two liquid process products, a partial condensate (PK) and a total condensate (TK), wherein the condensation leading to the formation of PK is performed with higher condensation than the temperature leading to the formation of TK, a product stream originating from PK and one originating from TK are each passed separately into a distillation column consisting of at least one stripping section and at least one rectifying section, the product stream originating from PK being introduced into the lower section of the distillation column between the lowermost stripping section and the section which follows, and the product stream originating from TK into the top of the distillation column above the uppermost rectifying section, and the desired purified aniline being withdrawn in a sidestream between lowermost stripping section and uppermost rectifying section of the distillation column. |
