Synthesis of Acetic Acid (Monsanto Process)
CH3OH + CO → CH3COOH
Visão geral
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.

Exemplo do cotidiano
White vinegar contains approximately 5% acetic acid, though commercial vinegar is typically produced by fermentation rather than this industrial process.
Importância industrial
Mais de 16 milhões de toneladas de ácido acético são produzidas anualmente usando este processo. O ácido acético é utilizado na produção de acetato de vinilo, anidrido acético, acetato de celulose e como solvente.
