    摘要: Anhydrous, solid Raney catalysts in fusible, organic embedding media prepared by initially introducing a Raney catalyst slurry into a vacuum mixer under an inert gas atmosphere, admixing the embedding medium, removing the main quantity of the water at temperatures below the melting point of the embedding medium and removing the residual water above the melting point of the embedding medium in vacuum while maintaining mixing. After the dehydration, the vacuum is terminated by applying an inert gas and the product where called for is shaped into low-surface molded bodies.
