Abstract:
The present invention provides a method for producing methyl acetate, and the method comprises a step in which dimethyl ether and a raw gas containing carbon monoxide and hydrogen go through a reactor loaded with a catalyst for carrying out a carbonylation reaction; wherein the catalyst contains an acidic EMT zeolite molecular sieve. The present invention has provided a new method for producing methyl acetate. In the method of the present invention, the carbonylation is carried out in the presence of the catalyst containing the acidic EMT zeolite molecular sieve, and the reaction activity is high, and the stability has been significantly improved, meeting the requirement of industrial production.
