摘要： MANUFACTURE OF CATALYSTS BY CONTACTING A MANGANESE OXIDE PRECIPITATE CONTAINING BOUND ALKALI (ESPECIALLY A PRECIPITATE OBTAINED BY REDUCTION OF A PERMANGANATE WITH FORMALDEHYDE) WITH A SALT OF COBALT, COPPER, SILVER OR LEAD, TO REPLACE THE ALKALI BY THE HEAVY METAL. USE OF THE CATALYSTS IN REDUCING NITRO COMPOUNDS TO NITROSO, AZO, AZOXY OR AMINO COMPOUNDS.

摘要： A PROCESS FOR THE MANUFACTURE OF AN AROMATIC PRIMARY AMINE BY REACTING IN THE PRESENCE OF A CATALYST AN AROMATIC NITRO COMPOUND AND A REDUCING AGENT SELECTED FROM THE CLASS CONSISTING OF: (A) HYDROGEN AND (B) CARBON MONOXIDE AND WATER OR ALIPHATIC ALCOHOL, AT A TEMPERATURE IN THE RANGE OF 100* TO 200* C., THE IMPROVEMENT WHICH COMPRISES UTILIZING AS THE CATALYST, ONE CONSISTING ESSENTIALLY OF TWO OR THREE HEAVY METALS SELECTED FROM THE GROUP CONSISTING OF MANGANESE, IRON, COBALT, NICKEL, COPPER, SILVER AND CERIUM AS THEIR OXIDES, HYDROXIDES OR CARBONATES, THE CATALYST BEING PREPARED BY EITHER CO-PRECIPITATION FROM SOLUTION OR A HEATING TOGETHER OF THE SAID HEAVY METALS AS THEIR HYDROXIDES OR HEAT-UNSTABLE SALTS OR MIXTURES THEREOF.
