Zur katalytischen Ketonisierung von Äthanol in Gegenwart von Wasserdampf

Abstract: Mit Hilfe einer kontinuierlich arbeitenden Apparatur wurde die nach der Brutto gleichung 2 C2H5OH + H2O = CH3COCH3 + CO2 + 4 H2 verlaufende Ketonisierung von Äthanol durch Wasserdampf in Gegenwart eines alkalisierten ZnOCr2O3‐Katalysators bei Temperaturen zwischen 270 und 460°C untersucht. Das Molverhältnis der Äthanol/Wasser‐Mischungen variierte zwischen 1:1 und 1:11. Die Versuchsergebnisse ermöglichten, die bisherigen Vorstellungen über den Chemismus des Prozesses zu vertiefen und vermeintliche Widersprüche… Show more

“…To design new catalytic reactions affording propene, our attention was paid to the formation of ketones from alcohols in which C x ‐alcohols are converted into C 2 x −1 ‐ketones; for example, ethanol to acetone on ZnO–Fe 2 O 3 , and so on,7, 12 and 1‐propanol to 3‐pentanone on CeO 2 –Fe 2 O 3 13. The reaction pathways yielding ketones are suggested as Equations (1) and (2) (or 2′) 7.…”
