Experiment 19.5: Catalysis of Acetone Oxidation by Copper
A red-hot copper coil is fixed over acetone in a beaker.
The coil glows with fluctuating intensity and in changing colors from black to light orange. There is also the typical pungent fruity smell of aldehyde.
Acetone is oxidized to acetaldehyde, carbon dioxide and water
The reaction is heterogeneously catalyzed by copper. The catalytic surface processes are visible by the fluctuating glowing and the changing colors of the copper coil.
