Borides, as catalysts

Levy et al.5 and Kaufman and Sen3 investigated cobalt and nickel borides as catalysts for controlled generation of H2 from NaBH, solutions. Brown and Brown6 investigated various metal salts and found that ruthenium and rhodium salts liberated H2 most rapidly from borohydride solutions. These results, along with our own work, indicated that ruthenium would most likely be the most active metal for catalysis of... [Pg.76]

High yields of primary amines have also been obtained over cobalt boride as catalyst,26,53,54 which has been found to be not only highly selective but also less inhibited by solvent and ammonia than other cobalt and nickel catalysts in hydrogenation of nitriles.26 The hydrogenation of propionitrile in isopropyl alcohol over cobalt boride (5% on C) in the presence of 15 1 molar ratio of ammonia to the nitrile gave propylamine in a high yield of 99% (eq. 7.29). [Pg.263]
