Abstract

L'invention concerne un procédé de préparation de composés aromatiques mononitrés dans un système de solvant biphasique liquide-liquide comprenant de l'acide nitrique aqueux comme première phase et des liquides ioniques (LI) comme seconde phase, l'acide nitrique étant échangé en continu pendant la réaction, ou l'eau générée pendant la réaction étant éliminée par addition de NO2 et d'un agent d'oxydation pendant la réaction.
