摘要: A description is given of the preparation of hydroxybiphenyl by dehydrogenation of completely or partially hydrogenated precursors using a supported Rh catalyst which additionally contains chromium, manganese and alkali metal and can contain a sulphur compound. The Rh catalyst which can be used according to the invention is prepared from halide-free starting materials. The Rh catalyst is distinguished by a low dependence of the initial selectivity, with the selectivity in the run-in state and the running-in time on the conditions of the reductive pretreatment and requires only short running-in times to reach the optimum state.

摘要: Noble metal/reducible metal oxide catalysts effective for the direct amination of aromatic hydrocarbons and heterocyclic analogs thereof are disclosed. In one embodiment, the cataloxidant comprises a noble metal selected from Pd, Rh, Ir and/or Ru and a reducible metal oxide. In another embodiment, the cataloxidant comprises a noble metal and a reducible oxide of a metal selected from Ni, Mn, V, Ce, Th, Pr, Te, Re, Co, Fe, Cu and/or Bi. A preferred cataloxidant comprises one or more noble metals selected from Pd, Rh, Ir and/or Ru, in combination with nickel oxide and/or manganese oxide. In preferred applications, benzene can be aminated in the presence of the cataloxidants to form aniline. A benzene conversion of at least 5% is achieved, with more than 90% selectivity for aniline. Significantly, the cataloxidant can be regenerated without a substantial loss of performance.
