Oxidative secondary rhodium recovery process |
| abstract |
Oxidation process intended to recover precious quantities of rhodium catalysts in "tars" formed during the preparation of acetic anhydride by rhodium-catalyzed carbonylation of a mixture of methyl iodide and methyl acetate and / or dimethyl ether. Said method comprises the treatment of a tar / methyl iodide solution which contains precious quantities of rhodium not normally extracted by aqueous hydrogen iodide, with a solution of hydrogen peroxide and acetic acid. |
