PROCESS FOR THE PRODUCTION OF ACETIC ACID

摘要

Process for producing acetic acid by carbonylating methanol and/or a reactive derivative thereof with carbon monoxide in at least one carbonylation reaction zone containing a liquid reaction composition containing an iridium carbonylation catalyst, methyl iodide co-catalyst, a finite concentration of water, acetic acid, methyl acetate. Indium and rhenium are present as promoters.
