Abstract

La présente invention concerne un procédé de préparation de canthaxanthine. Selon l'invention, on oxyde de l'isozéaxanthine ou de la 4'-hydroxyéquinénone avec un sel de l'acide chlorique ou de l'acide bromique en présence des halogènes brome ou iode, ou bien des oxydes ou des acides oxo du sélénium, des éléments des groupes Va, Via ou VIIa du système périodique, ou des sels de ces acides oxo ou des oxydes des éléments du groupe VIII du système périodique servant de catalyseur ou d'un liant ou d'un solvant inertes à une température comprise entre 0 et 100 degrés C.The present invention relates to a process for the preparation of canthaxanthin. According to the invention, isozeaxanthin or 4'-hydroxyequinenone is oxidized with a salt of chloric acid or bromic acid in the presence of bromine or iodine halogens, or else oxides or oxo acids of selenium , elements of groups Va, Via or VIIa of the periodic system, or salts of these oxo acids or oxides of elements of group VIII of the periodic system serving as a catalyst or a binder or a solvent inert at a temperature included between 0 and 100 degrees C.
