  • Patent number: 6017507
    Abstract: A process is provided for reducing the amount of hydrogen sulfide present in a tail gas from a sulfur recovery process. The hydrogen sulfide contaminated gas along with a gas containing free oxygen is passed through a series of hydrogen sulfide oxidation zones containing an oxidation catalyst, such as one or more oxides or salts of Ni, Co, Fe, Cu, Ag, Mn, Mo, Cr, W and V, deposited on a support, such as bauxite, activated alumina, titania and activated carbon. The initial and intermediate catalyst beds are operated adiabatically by injecting a substoichiometric amount of oxygen into the gas to be treated with respect to the amount of hydrogen sulfide present in the gas so that the temperature does not exceed 150.degree. C. The final catalyst bed is operated under conditions such that a superstoichiometric amount of oxygen is injected into the gas with respect to the hydrogen sulfide and cooling is provided so that the temperature does not exceed 150.degree.

  • Patent number: 6013796
    Abstract: For the synthesis of 3-methylnaltrexone from codeine in this invention, codeine is converted to 6-acetylcodeine, which is N-demethylated to 6-acetylcodeine hydrochloride, followed by alkylating the nitrogen to form 17-cyclopropylmethylnorcodeine. The latter is oxidized to 17-cyclopropylmethylnorcodeinone. For the synthesis of naltrexone from morphine in this invention, morphine is converted to 3-benzylnormorphine as described above in the synthesis of noroxymorphone. 3-Benzylnormorphine is reacted with cyclopropylmethyl halide to produce 3-benzyl-17cyclopropylmethylnormorphine, a novel compound, which is oxidized to 3-benzyl-17-cyclopropylmethyl-normorphinone, a novel compound, by Swern oxidation.
