Abstract:Carbonylation of ethanol using homogeneous rhodium complex catalysts is an essential route for the manufacture of propionic acid, as carbonylation of methanol to acetic acid is a large‐scale commercial process that could provide critical insights for the ethanol carbonylation process. The reaction mechanism of ethanol has not been well understood yet, and the high cost of downstream separation due to high water content is still worrying. Consequently, propionic acid was used as solvent to reduce water content … Show more
“…4,5 In addition, the vapor phase carbonylation of ethanol has appropriate reaction conditions and the product is easily separated from the catalyst. 6,7 Nickel-based and rhodium-based catalysts are the most common monometallic catalysts for vapor phase carbonylation of ethanol. Although a rhodium-based catalyst has high catalytic activity, 8 its cost is high.…”

Vapor phase carbonylation of ethanol is an effective way to produce propionic acid. Monometallic nickel-based catalysts stand out because of their low preparation cost and relatively high catalytic performance. However,...
