Palladium on carbon, often referred to as Pd/C, is a form of palladium used as a catalyst in hydrogenations.
How to use Pd/C
To be added
A video showing the procedure can be found here.
Pd/C is sold by various lab suppliers.
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%.
- Catalytic hydrogenation (reductive amination, carbonyl reduction, nitro compound reduction, the reduction of imines and Schiff bases, debenzylation reactions, etc.)
- Coupling reactions (Suzuki reaction, Stille reaction, etc.)
Handling and safety
Pd/C is highly reactive due to its high surface area, and when filled with hydrogen it may ignite in contact with oxygen.
