Platinum/Palladium on Carbon Catalysts
- Platinum/Palladium on Activated Charcoal, commonly known as Platinum/Palladium on Carbon, is a mild hydrogenation catalyst. It is typically the catalyst of choice when the functional group to be hydrogenated is part of a molecule containing other functional groups that are also capable of hydrogenation.
- Platinum/Palladium on Carbon is particularly favored for achieving specific types of isomers, making it a catalyst for selective hydrogenation. Additionally, it can be safely used under acidic reaction conditions, such as when acetic acid is used as a solvent, or when dilute sulfuric acid or hydrochloric acid is present as additives.
Safety, Storage, Shelf Life, Handling, and Disposal of Platinum/Palladium on Carbon Catalyst
- Platinum/Palladium Catalyst (Active) is highly pyrophoric when it dries upon exposure to air, atmosphere, or oxygen. Therefore, it should always be kept under demineralized or distilled water.
- Hydrogen gas continuously evolves from the catalyst slurry. Smoking, lighting cigarettes, bidis, matchsticks, or lighters should be strictly prohibited. It should be stored in a cool, well-ventilated place, protected from direct sunlight.
- Manually stir the catalyst slurry with a plastic or glass rod or spoon to maintain suspension for easy and smooth transfer. Exercise care to avoid or minimize spillage during the transfer of the catalyst. When transferring the catalyst from containers to the reaction vessel, always use protective gloves, shoes, and goggles.
- In case of a spillage, collect the spilled catalyst slurry manually, place it in a polyethylene bag, then pack it in a plastic or M.S. container. Flush the area from which the catalyst was retrieved with water. As an additional measure, a 0.5% potassium permanganate (KMnO4) solution may be used.
- If the catalyst comes into contact with skin, wash the affected area immediately with running water, dry it with a clean towel, and apply a soothing ointment (e.g., Soframycin). Thoroughly wash empty polyethylene bags and containers with water before discarding them after catalyst transfer.
Disposal Precautions:
Platinum/Palladium is a costly metal. Do not discard spent Platinum/Palladium Catalysts that cannot be reactivated. You can contact Bangalore Refinery Private Limited to get a good value.
