Abstract

L'invention a pour objet un procédé de préparation d'une N,N'-dialkyl-phénylènediamine comprenant une alkylation réductrice d'une nitroaniline par une cétone en présence d'hydrogène et d'un catalyseur d'hydrogénation dans des conditions de réaction et la récupération de la N,N'-dialkyl-phénylènediamine résultante, caractérisé en ce qu'on effectue la réaction d'alkylation en présence d'un solvant organique comprenant un éther choisi parmi des monoéthers et diéthers de dialcools et des diéthers cycliques.
