Vinegar Production from Methanol

This report provides the economy of producing Vinegar using a rhodium-catalysed carbonylation process. It is produced via methanol carbonylation using fossil-based CO. Initially, recycled rhodium catalyst is treated to recover the rhodium and is then mixed with fresh catalyst, a promoter (methyl iodide) and a stabilizer (iodide salt). The mixture is then dissolved in hot acetic acid under pressurized carbon monoxide. The reactor is fed with the catalyst solution, methanol and carbon monoxide, along with recycle streams. The reaction occurs in the liquid phase, where dissolved carbon monoxide combines with methanol to yield acetic acid.
