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.
