Production Process –

Majority of this organic compound is produced via methanol carbonylation, wherein a reaction between methanol and carbon monoxide produces acetic acid.

CH3OH + CO → CH3COOH

There are two related processes for methanol carbonylation: the rhodium-catalyzed Monsanto process, and the iridium-catalyzed Cativa process. The Cativa process is considered to be more efficient and eco-friendly. 

The second most preferred method of producing acetic acid is via oxidation of acetaldehyde. Acetaldehyde is produced via oxidation of butane or light naphtha, or by hydration of ethylene. When butane or light naphtha is heated with air in the presence of various metal ions, peroxides form and then decompose to produce acetic acid. 

2 C4H10 + 5 O2 → 4 CH3COOH + 2 H2O

Some other methods of producing acetic acid include anaerobic fermentation, ethylene oxidation and oxidative fermentation.
