Palladium on carbon
Palladium on carbon, Pd/C, Pd-C
3D model (JSmol)
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
Palladium on carbon is used for catalytic hydrogenations in organic synthesis. Examples include reductive amination, carbonyl reduction, nitro compound reduction, the reduction of imines and Schiff bases and debenzylation reactions.
Palladium chloride and hydrochloric acid are added to a warmed, aqueous suspension of activated carbon. Formaldehyde is then added to the solution followed by neutralization with sodium hydroxide. Finally the catalyst filtered, washed with distilled water, and dried over potassium hydroxide. Palladium loading is typically between 5% and 10%.
