ABSTRACT:
A process for recovering Group VIII metals from process streams derived from carbonylation processes is provided. The process comprises contacting the process stream with an extracting stream comprising acetic acid in water and thereafter recovering the extracting stream. The process stream is preferably one which contains tar and is produced by diluting a side stream from a carbonylation reactor with methyl iodide. During the process the Group VIII metal is extracted into the extracting stream from the process stream.
