FIELD: chemistry.
SUBSTANCE: invention relates to a method for combined production of acetic acid and dimethyl ether by dehydration-hydrolysis of a feed mixture of methanol and methyl acetate in the presence of at least one catalyst to obtain a crude reaction product containing acetic acid and dimethyl ether, in which the raw material for said combined production method contains methanol, methyl acetate and dimethyl ether, in which dimethyl ether is present in the raw material in a total amount of 25 mol. % or less in terms of all raw materials.
EFFECT: disclosed is a method for combined production of acetic acid and dimethyl ether.
