Abstract
From a synthesis gas mainly consisting of hydrogen and carbon oxides an acetic acid product consisting of acetic acid, acetic anhydride and/or methyl acetate is prepared by reactions known per se in a technically simple reaction sequence and a high conversion degree when the reactions are combined such that in a first step at a pressure of 5-200 bar and a temperature of 150.degree.-400.degree. C. the synthesis gas is converted in the gas phase in a first reactor to methanol, of which at least a substantial proportion is converted to dimethyl ether in the same reactor in the presence of one or more catalysts which together catalyze the reactions
