Direct synthesis of methyl acetate and acetic acid from syngas over tandem catalysts composed of a Cu-based catalyst and a Cu-exchanged mordenite zeolite

Tandem catalysts composed of a Cu-based methanol synthesis catalyst and a mordenite zeolite-based DME carbonylation catalyst converted syngas to methyl acetate and acetic acid with high selectivity at 230 °C and 5 MPa.
