Process for purifying aniline from gas phase hydrogenations

Process for purifying aniline from gas phase hydrogenations

The invention relates to a process for purifying aniline produced by gas-phase hydrogenation of nitrobenzene, by fractional condensation of the crude reaction product obtained in gaseous form so that at least two liquid process products, a partial condensate (PK) and a total condensate (TK), are obt...
