摘要： 1,201,050. Hydrogenation catalysts. IMPERIAL CHEMICAL INDUSTRIES Ltd. 7 Nov., 1968 [24 Nov., 1967], No. 53636/67. Heading B1E. [Also in Division C2] A catalyst comprising two or more heavy metals as defined, as their oxides, hydroxides or carbonates or partial reduction products thereof, which has been prepared by a procedure including as a step either a coprecipitation or a heating together of the heavy metals as their hydroxides or heat unstable salts is used in the preparation of amines by reduction of aromatic nitro compounds. By heavy metals is meant Ti, V, Mn, Fe, Co, Ni, Cu, Ge, Zr, Mo, Ag, Sn, Sb, La, Ce, Nd, W, Au, Hg, Tl, Pb, Bi and Th. In examples the metal combinations used are Mn and Ag, Cu and Ce, Cu and Mn, Fe and Co, Mn, Ni and Co, Ce andÀFe, Fe and Cu, Mn and Fe. Other metal combinations referred to are Ni and Mn, Ag and Ti, Pb and V, Sn and Mn, Bi and Mn, W and Ce, Th and Ce, Au and Mn, Mo and Ce, Cu and La, Ag, Pb and Mn, Hg, Pb and Mn, Ti, Pb and Mn.
