ABSTRACT:
A process is described for removing copper and manganese ions from a saturated aliphatic monocarboxylic acid containing from 6 to 9 carbon atoms by extracting the metal ions into an aqueous layer in the presence of an extractant acid, the hydrogen of which can be replaced by both metal ions. The metal ion-containing aqueous layer may then be separated from the monocarboxylic acid-containing organic layer, with the latter layer having a substantially reduced content of copper and manganese ions.
