Abstract
1. A process for the preparation of acetic anhydride and possibly acetic acid by reaction of carbon monoxide and possibly hydrogen with methyl acetate and/or dimethylether, possibly as a mixture with methanol and/or water, at temperatures from 350 to 575 K and pressures from 1 to 300 bar in the presence of a catalyst system consisting of noble metals of group VIII of the periodic table of the elements or compounds thereof, iodine and/or compounds thereof and possibly carbonylforming base metals from groups IV, V, VI, VII or VIII of the periodic table of the elements or compounds thereof and possibly an aliphatic carboxylic acid having 1 to 4 carbon atoms, wherein the catalyst system contains tetrabutylphosphonium iodide as an additional promoter.
