Method for producing methyl acetate by means of carbonylation of dimethyl ether

A method for producing methyl acetate by carbonylation of dimethyl ether comprising, feeding dimethyl ether and a feeding gas containing carbon monoxide into a reactor equipped with a solid acid catalyst to react to produce methyl acetate;

• wherein, a molar ratio of carbon monoxide to dimethyl ether ranges from 0.05:1 to 0.5:1;
• wherein the solid acid catalyst comprises at least one of a zeolite molecular sieve and a modified zeolite molecular sieve;
• wherein, a framework type of the zeolite molecular sieve is one of FER, MFI, MOR, ETL, MFS, MTF, and EMT;
• and a modification refers to at least one of element modification in which the element refers to the one other than elements constituting a framework of zeolite molecular sieve, pyridine modification, organic amine modification, alkyl ammonium halide salt modification, acid treatment, steam treatment, and ammonium ion exchange;
• wherein the zeolite molecular sieve is hydrogen type zeolite molecular sieve;
• wherein a content of the hydrogen type zeolite molecular sieve in the solid acid catalyst ranges from 10 wt % to 100 wt %.
