FIELD: chemistry.
SUBSTANCE: invention relates to a method for combined production of acetic acid and dimethyl ether, comprising a step of reacting methyl acetate with methanol in the presence of a catalyst comprising a crystalline zeolite having a FER-type framework structure, where the zeolite crystallites have a size on the c axis of about 500 nanometers (nm) or less, and a ratio of the size along the c axis to the size along the b axis greater than or equal to 5:1.
EFFECT: disclosed are dehydration-hydrolysis methods and catalysts therefor.
