摘要 |
<p>For the recovery of rhodium from the distillation residues of crude oxosynthesis products, the residue, or the feed material containing the residue, is treated with oxygen or an oxygen-containing gas in the presence of a monocarboxylic acid having 2 to 5 carbon atoms and of an alkali metal salt of a monocarboxylic acid having 2 to 5 carbon atoms.
