ABSTRACT:
A process for the production of acetic acid by carbonylation of methanol or a reactive derivative thereof by contacting the methanol or derivative with carbon monoxide in a liquid reaction composition comprising (a) acetic acid, (b) an iridium catalyst, (c) methyl iodide, (d) at least a finite quantity of water and (e) methyl acetate is improved by the use as promoter of at least one of ruthenium and osmium.
