Safety, Storage, Shelf Life, Handling and Disposal

  • Raney Nickel Catalyst (Active) is highly pyrophoric when it gets dried up on exposure to air/ atmosphere/ oxygen. It should therefore always be kept under demineralised/ distilled water.
  • The containers of the catalyst should be stored in a cool and ventilated place protected from direct exposure to sunlight.
  • Protective gloves, shoes and goggles must be used while transferring catalyst from containers to the reaction vessel.
  • Hydrogen gas continuously evolves from the catalyst slurry. Smoking cigarette/ bidi and lighting matchstick/ lighter should be strictly prohibited while opening the containers of the catalyst.
  • The catalyst slurry should be manually stirred using a steel rod / spoon to restore it in suspension for easy and smooth transfer.
  • Care should be taken while transferring catalyst so as to avoid/ minimise spillage of the catalyst. skilled personnel should be employed for handling the catalyst.
  • In the event of spillage of small quantity, the spilled material may be deactivated by using a 0.5 % solution of potassium permanganate followed by flushing the area with sufficient water.
  • In the event of spillage of significant quantity, the spilled catalyst slurry should be collected back manually and put in a polythene bag thereafter be packed in a plastic or M.S.Container and retrieval of the spilled catalyst should be flushed with water. A 0.5 % solution of Potassium Permanganate [KMnO4] may also be used as an additional measure.
  • In the event of contact with skin, the skin should be washed immediately with running water. Dry with a clean towel and apply a soothing ointment (viz soframycin).
  • Empty polythene bags and containers after transfer of catalyst should be washed profusely with water before scrapping them.
  • Great care should be taken in deciding temperature and pressure condition and selection of solvent for the hydrogenation reaction.


Nickel is a costly metal. Do not therefore discard even such of the spent Raney Nickel Catalysts which can not be reactivated any more.

Even such a material can fetch good money from the manufacturers of Nickel salts.
