FIELD: chemistry.
SUBSTANCE: invention relates to a method of increasing efficiency and catalyst stability when producing methyl acetate, involving carbonylation of dimethyl ether based material 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 275°C to 350°C, and in the presence of hydrogen.
EFFECT: high efficiency and catalyst stability.
