Synthesis of Acetic Acid (Monsanto Process)
CH3OH + CO → CH3COOH
Tổng quan
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.

Ví dụ thực tế
White vinegar contains approximately 5% acetic acid, though commercial vinegar is typically produced by fermentation rather than this industrial process.
Tầm quan trọng công nghiệp
Over 16 million tonnes of acetic acid are produced annually using this process. Acetic acid is used to make vinyl acetate, acetic anhydride, cellulose acetate, and as a solvent.
