摘要: A Raney catalyst composition which has ice as a solid carrier. The reaction involving the Raney catalyst of the invention is carried out by portionwise adding a Raney catalyst containing ice as solid carrier to the reaction mixture. The operation-safe cylindrical or angular vessel used for the storage and/or handling of the Raney catalyst has a conical casing or side walls joining to the bottom through a bend radius of greater than 0.5 mm. The vessel is covered by a tightly closing cap.
