FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing acetic acid and specifically to a method of producing acetic acid via carbonylation in the presence of a rhodium catalyst system. Described is a catalyst system for producing acetic acid, which includes a carbonylation rhodium catalyst, methyl iodide, at least one heteropolyacidic promoter and a method of producing acetic acid through carbonylation of methanol and/or its reactive derivative with carbon monoxide in a liquid reaction mixture which contains methyl acetate, limited concentration of water, acetic acid and the catalyst system mentioned above.
EFFECT: faster carbonylation.
