Abstract (en)
[origin: EP0117371A1] 1. Process for the preparation of aminobenzoic acids, of the type comprising a first stage of oxidation of the nitrotoluenes into nitrobenzoic acids, followed by a second stege of electro-chemical reduction of said nitrobenzoic acids, characterized in that the oxidising agent used for carrying out the first stage is a sulphochromic solution which is regenerated at the anode of an electrolyser simultaneously providing the electro-chemical reduction of the second stage, said second stage of electro-chemical reduction being conducted in an electrolyser in which the anodic and cathodic compartments are separated by a membrane.
