  A catalytic process for hydrogenating aromatic di- and polyamines with the aid of a selected catalyst system is provided, which comprises a mixture of a first heterogeneous catalyst and a second heterogeneous catalyst and a nitro compound (nitrate and/or nitrite salt). The first and second heterogeneous catalyst each independently comprise a metal selected from the group consisting of Cr, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd and/or Pt and the metal selected for the second heterogeneous catalyst is different from the metal selected for the first heterogeneous catalyst. Hydrogenation of aromatic rings having two or more amino groups bound to the aromatic ring produces cycloaliphatic di- and polyamines, which are useful chemical intermediates, e.g., for further reaction with epoxides or isocyanates. The amino groups may also be converted to isocyanates via reaction with phosgene. The resulting cycloaliphatic di- and polyisocyanates may also be used as monomers for making polymers.

  提供了一种催化氢化芳香族二元和多元胺的过程，该过程借助于一个选定的催化剂系统，其中包括第一异相催化剂和第二异相催化剂的混合物以及硝基化合物（硝酸盐和/或亚硝酸盐）。第一和第二异相催化剂各自独立地包含从Cr、Mo、W、Mn、Re、Fe、Ru、Os、Co、Rh、Ir、Ni、Pd和/或Pt组成的金属，并且第二异相催化剂选择的金属与第一异相催化剂选择的金属不同。氢化具有两个或更多氨基固定在芳香环上的芳香环产生环脂肪族二元和多元胺，这些是有用的化学中间体，例如，用于与环氧化物或异氰酸酯进一步反应。氨基团也可以通过与光气反应转化为异氰酸酯。所得到的环脂肪族二元和多元异氰酸酯也可以用作制造聚合物的单体。

  A process for hydrogenating aromatic di- and polyamines is provided comprising the steps of reacting the aromatic amine with hydrogen in the presence of a catalytic system, wherein the catalytic system comprises a heterogeneous catalyst comprising a metal selected from the group consisting of Cr, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd and/or Pt and a support, and wherein the catalyst system further comprises an organic nitro compound. Hydrogenation of aromatic di- and polyamines having two or more amino groups bound to the aromatic ring produces cycloaliphatic di- and polyamines, which are useful chemical intermediates, e.g., for further reaction with epoxides or isocyanates. The amino groups may also be converted to isocyanates via reaction with phosgene. The resulting cycloaliphatic di- and polyisocyanates may also be used as monomers for making polymers.
