FIELD: chemistry.
SUBSTANCE: method involves carbonylation of methanol and/or its reactive derivative with carbon monoxide in at least one carbonylation reaction zone, containing al liquid reaction composition which contains an iridium carbonylation catalyst, acetic acid, methyl acetate, ruthenium - promoter, and indium - catalyst system stabiliser, selected from indium, where the molar ratio iridium/promoter/stabiliser in the liquid reaction composition is kept in the interval 1:(from >2 to 15):(from 0.25 to 12).
EFFECT: using of indium as a catalyst system stabiliser in a method of producing acetic acid.
