Abstract:
The invention relates to a method for producing aniline or products that are obtained by further chemical reaction of aniline (aniline derivatives), involving decarboxylation of aminobenzoic acid, particularly ortho-aminobenzoic acid, in which one portion of the previously formed crude aniline is recirculated in the decarboxylation step. The aminobenzoic acid is obtained enzymatically or chemically, preferably enzymatically.
