FIELD: chemistry.
SUBSTANCE: invention relates to an improved method of reducing formation of byproducts when producing methyl acetate, which involves carbonylation of dimethyl ether with carbon monoxide in one or more carbonylation reaction zones in the presence of a mordenite catalyst to obtain a methyl acetate product, characterised by that at least one of methyl acetate and acetic acid is fed into at least one of said reaction zones.
EFFECT: improved method of reducing formation of byproducts when producing methyl acetate.
