Abstract
Acetic acid is produced by reacting methanol with carbon monoxide in the presence of hydrogen, in the presence of a catalyst comprising a molybdenum-nickel or a tungsten-nickel cocatalyst component, in the presence of an iodide, and in the presence of a promoter comprising an organo-phosphorus compound or an organo-nitrogen compound, the ratio of the partial pressure of hydrogen to the partial pressure of carbon monoxide in the reaction zone being 0.05 to 0.4.
