FIELD: chemistry.
SUBSTANCE: invention relates to an improved method of increasing rate of reaction without a ruthenium promoter and reducing toxicity of the catalyst system when producing acetic acid via carbonylation of methanol and/or reactive derivative thereof with carbon monoxide in at least one carbonylation reaction zone, containing a liquid reaction composition which contains an iridium carbonylation catalyst, a methyl iodide cocatalyst, water in an a limited concentration, acetic acid, methyl acetate and indium and rhenium as promoters.
EFFECT: high efficiency of the method.
