  • Method for producing aminobenzoic acid or an aminobenzoic acid derivative
    Patent number: 11168341
    Abstract: The invention relates to a method for producing aminobenzoic acid or a aminobenzoic acid derivative via the fermentation of a suitable raw material under the influence of suitable microorganisms and obtaining a fermentation broth containing aminobenzoate and/or aminobenzoic acid. In particular, the invention relates to the step of obtaining the aminobenzoic acid from the fermentation broth, wherein the crystallisation of aminobenzoic acid is carried out via a simple one-stage acid treatment in the presence of seed crystals. The aminobenzoic acid crystallised in this simple manner can be easily separated from the mother liquor, further cleaned if necessary, and then supplied to the different applications.
