Degussa H 1201
Fixed Bed Catalyst - Copper/Chrome on Silica
Description
H 1201 is a highly active Cu-Cr catalyst for dehydrogenation of alcohol to carbonylic compounds or hydrogenation of ketones to alcohols, respectively.
The special silica carrier will not lead to dehydratisation reactions.
H 1201 is also available in smaller sizes.
Active Component (s) Cu, Cr
Shape Granules, 4 - 7 mm
Support silica

Dehydrogenation of Alcohols to Aldehydes or Ketones
Fixed Bed Catalysts
EtOH --> acetaldehyde
Comments to reaction scheme:
Primary and secondary alcohols can be dehydrogenated to give corresponding aldehydes and ketones. The type of catalyst depends on the alcohol. Slow poisoning may occur due to side reaction products and water. The reaction can be carried out in vapor or liquid phase.
Base metal: Copper chromite, Copper alumina, ZnO/CuO catalyst choice depends on reactant)
Conditions
Temperature range [ºC] 200-450 °C
Pressure range [bar] 1-3
