Abstract

original image

Alles Essig: Die selektive Oxidation von Ethanol zu Essigsäure gelingt in wässriger Lösung mit dem Oxidans Luft an einem Gold-Heterogenkatalysator (siehe Bild). Bei 423 K und einem O2-Druck von 0.6 MPa verläuft diese Reaktion glatt in saurer wässriger Lösung in Ausbeuten um 90 %. CO2 ist das einzige Nebenprodukt, das in nennenswerten Mengen entsteht.
