FIELD: chemistry.
SUBSTANCE: catalytic system for obtaining acetic acid includes iridium carbonilation catalyst, methyliodide co-catalyst, non-obligatory, at least one of the following elements: ruthenium, osmium, rhenium, zinc, gallium, tungsten, cadmium, mercury and indium, ant, at least, one promoter - non-halogenohydrogen acid. Non-halogenohydrogen acid can represent oxo-acid, superacid and/or hateropolyacid. Method of obtaining acetic acid by reaction of carbon monoxide with methanol and/or its reaction-able derivative in liquid reaction composition, which includes methylacetate, water in limited concentration, acetic acid and said catalytic system, is described. Application of catalytic system for obtaining acetic acid is described.
EFFECT: increasing rate of carbonilation.
