Title (EN) PRODUCTION OF ANILINE VIA ANTHRANILATE
(FR) PRODUCTION D'ANILINE PAR L'INTERMÉDIAIRE D'ANTHRANILATE
Abstract: front page image
(EN)The invention relates to a method for producing aniline, comprising the steps of: a) providing o-aminobenzoate, wherein said o-aminobenzoate comprises anthranilate anion and a suitable cation, b) converting said anthranilate anion to aniline by thermal decarboxylation in the presence or absence of a catalyst, c) extracting the aniline produced in step b) in an organic solvent at least once, and d) purifying the aniline produced in steps b) and c) by distillation, wherein said distillation produces aniline and a water phase.
(FR)L'invention concerne un procédé de production d'aniline, comprenant les étapes suivantes : a) fournir de l'o-aminobenzoate, cet o-aminobenzoate comprenant un anion anthranilate et un cation approprié, b) convertir ledit anion anthranilate en aniline par décarboxylation thermique en présence ou en absence d'un catalyseur, c) extraire l'aniline produite dans l'étape b) dans un solvant organique au moins une fois, et d) purifier l'aniline produite dans les étapes b) et c) par distillation, ladite distillation produisant l'aniline et une phase aqueuse.
