Acetic Acid Manufacture from Methanol

Acetic Acid (aka. Ethanoic Acid) is a carboxylic acid found in dilute solutions in plant and animal systems. This chemical is widely used in organic processes, primarily in the production of vinyl acetate monomer and acetic anhydride.

Technology Description

The following paragraphs describe a process for Acetic Acid production from methanol and carbon monoxide, based on rhodium-catalyzed carbonylation. The figure below presents a simplified flow diagram of the process.
