VERFAHREN ZUR HERSTELLUNG VON ESSIGSAEURE, METHYLACETAT, ACETANHYDRID ODER MISCHUNGEN DAVON

摘要

The present invention relates to a process for preparing acetic acid, acetic acid methyl ester or acetic anhydride or mixtures thereof by converting a synthesis gas mainly containing hydrogen and carbon oxides, by first converting the synthesis gas catalytically into a gas mixture containing methanol and dimethyl ether and then carbonylating this mixture catalytically into acetic acid and/or methyl acetate and/or acetic anhydride.
