A method of removing organic iodides from non-aqueous organic media includes contacting the organic media with a silver or mercury-exchanged cationic ion exchange substrate at a temperature greater than about 50 ~C. The method is particularly effective for removing high molecular weight organic iodides from organic media such as acetic acid or acetic anhydride. Particular species removed include decyl iodides and dodecyl iodides from organic media such as acetic acid.

L'invention concerne un procédé d'élimination d'iodures organiques de milieux organiques non aqueux, qui consiste à mettre en contacter le milieu organique avec un substrat échangeur d'ions cationiques à échange d'argent ou de mercure à une température supérieure à environ 50 ·C. Le procédé est particulièrement efficace pour éliminer des iodures organiques à poids moléculaire élevé de milieux organiques, tels que l'acide acétique ou l'anhydride acétique. Parmi les espèces éliminées de milieux organiques, tels que l'acide acétique, figurent les iodures décyl et les iodures dodécyl.
