Abstract

1. Process for making acetic acid and optionally acetic anhydride by reacting methyl acetate and/or dimethylether with carbon monoxide or mixtures of carbon monoxide and hydrogen, at temperatures of 150 to 300 degrees C, under reaction pressures of more than 80 bar, in the presence of a catalyst system comprised of noble metals belonging to group VIII of the periodic system of the elements, or their compounds, and optionally tertiary or quaternary organonitrogen or organophosphorus compounds, which comprises using methyl chloride, chlorine or hydrogen chloride as an additional promoter.
