ABSTRACT:
Disclosed is a process for the recovery of noble metals from a catalyst-tar formed in a process in which acetic anhydride is prepared by carbonylating methyl acetate in the presence of a noble metal containing catalyst such as rhodium, lithium and methyl iodide. The rhodium is recovered from the tar formed in the process by treating the catalyst containing tar with a lower fatty acid at a temperature of at least 100.degree. C. thereby isolating the noble metal which precipitates from the tar.
