FIELD: chemistry.
SUBSTANCE: invention relates to a method of increasing efficiency and selectivity when producing methyl acetate, involving carbonylation of material based on dimethyl ether with carbon monoxide in virtually anhydrous conditions in the presence of a zeolite catalyst which is efficient in said carbonylation, wherein the reaction is carried out at temperature ranging from higher than 250 to 350°C, and at pressure ranging from higher than 10 to 100 bar (isobar).
EFFECT: high efficiency and selectivity when producing methyl acetate.
