Oxidative secondary rhodium recovery process |
摘要 |
Disclosed is an oxidative process for recovering rhodium catalyst values from "tars" formed during the preparation of acetic anhydride by the rhodium catalyzed carbonylation of a mixture of methyl iodide and methyl acetate and/or dimethyl ether. The disclosed process includes the treatment of a tar/methyl iodide solution, which contains rhodium values normally not extracted by aqueous hydrogen iodide, with a solution of hydrogen peroxide and acetic acid.
