Claim Text:
1. A method for preparing methyl acetate, in which a feed gas containing an organic amine, dimethyl ether, carbon monoxide and optional hydrogen gas goes through a reaction region loaded with a H-type mordenite catalyst, to produce methyl acetate at a reaction temperature range from 150° C. to 320° C., a reaction pressure range from 0.1 MPa to 8 MPa and a gas hourly space velocity range from 500h-1 to 10000h-1; wherein said H-type mordenite catalyst is a H-type mordenite catalyst with adsorption of an organic amine; in said feed gas, the molar ratio range of carbon monoxide to dimethyl ether is from 1:1 to 45:1, and the molar ratio range of the organic amine to dimethyl ether is from 0.00001:1 to 0.2:1, and the molar ratio range of hydrogen gas to dimethyl ether is from 0:1 to 20:1; said reaction region contains one reactor or reactors which are connected in series or in parallel; said organic amine is at least one selected from pyridines amines, aromatic amines or alicyclic amines.
