La présente invention a pour objet un nouveau procédé de préparation d'isovanilline.
Le procédé de préparation d'isovanilline selon l'invention est caractérisé par le fait qu'il consiste à effectuer la désalkylation à l'aide d'un acide fort, sélectivement en position 3, d'un 3-alkoxy-4-méthoxybenzaldéhyde dans lequel le groupe alkoxy a au moins deux atomes de carbone.
