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.

Process for the production of acetic acid

Catalyst system for the production of acetic acid comprising a rhodium carbonylation catalyst, methyl iodide and at least one heteropolyacid promoter.

Process and catalyst for the manufacture of acetic acid

A catalyst and process for the production of acetic acid by the carbonylation of methanol and/or a reactive derivative thereof. The catalyst system comprises an iridium carbonylation catalyst, methyl iodide co-catalyst, optionally at least one of ruthenium, osmium, rhenium, zinc, gallium, tungsten, cadmium, mercury and indium and at least one non-hydrohalogenoic acid promoter. The non-hydrohalogenoic acid may be an oxoacid, a superacid and/or a heteropolyacid.

Catalyst and process for the production of acetic acid

A process for the production of acetic acid by carbonylating methanol and/or a reactive derivative thereof with carbon monoxide in the presence of a promoted iridium carbonylation catalyst wherein the promoters are boron and gallium.

A process for the production of acetic acid by carbonylating methanol and/or a reactive derivative thereof with carbon monoxide in the presence of an iridium promoted carbonylation catalyst wherein the promoters are ruthenium and at least one of niobium and tantalum.
