Abstract
L'invention a pour objet un procédé de préparation d'un chlorure d'acide carboxylique aromatique, à l'aide d'une réaction en un seul stade, dans un solvant, d'un acide carboxylique aromatique ou son anhydride avec de l'oxyde de carbone et du chlore, en présence d'un catalyseur comprenant au moins un composé choisi parmi les chlorures et les oxydes de phosphines.The invention relates to a process for the preparation of an aromatic carboxylic acid chloride, using a single-stage reaction, in a solvent, of an aromatic carboxylic acid or its anhydride with carbon monoxide and chlorine, in the presence of a catalyst comprising at least one compound chosen from chlorides and oxides of phosphines.
