Synthesis of Acetic Acid (Monsanto Process)

CH₃OH + CO → CH₃COOH

Descripción general

Methanol reacts with carbon monoxide in the presence of a rhodium-iodide catalyst to form acetic acid. The Monsanto process (and its successor, the Cativa process using iridium) is the dominant industrial method for acetic acid production.
