Abstract
A catalyst and process for the production of methyl acetate by contacting dimethyl ether and carbon monoxide in the presence of a catalyst which is a zeolite of micropore volume of 0.01 ml/g or less.
Claims17
A catalyst for the carbonylation of dimethyl ether with carbon monoxide to produce methyl acetate wherein the catalyst comprises an dried but uncalcined crystalline microporous aluminosilicate zeolite of micropore volume of 0.01 ml/g or less and which zeolite
- is selected from zeolites of framework type MOR, FER, CHA, OFF, MFS and GME;
- is in an ion-exchanged ammonium or hydrogen form;
- and
- contains at least one channel which is defined by an 8-member ring,
- wherein an organic structure directing agent selected from salts and bases of quaternary ammonium compounds is used to prepare the zeolite, which is not subsequently removed from or not substantially removed from the zeolite as synthesized.
