    Possible selective effects of Interferon α-2b on a malignant clone in a case of polycythemia vera (1993)
    Springer
    Annals of hematology 66 (1993), S. 161-162 
    Details
    ISSN: 1432-0584
    Schlagwort(e): Polycythemia vera ; Interferon ; Translocation, IgA
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary A patient with polycythemia vera associated with chromosomal translocation (6; 8) (q27; p11) and IgA monoclonal gammopathy was treated with interferon α-2b. Interferon α-2b induced good hematological control and reduced only IgA levels, but not IgG and IgM levels. In addition, cytogenetic improvement was obtained, the abnormal cells with chromosomal translocation declining from 100% to 50%. Interferon a may have selective effects on a malignant clone in polycythemia vera.

    Beschreibung / Inhaltsverzeichnis: Abstract Заглавные реакции были исследованы с твердыми перекислотами, которые при-готовлялись обработкой Zr(OH)4 1 N-ой H2SO4 с поседуйщим обжигом при 650°C на воздухе. Пентан и изопентан превращалиь в изопент аи и изобутан, соответственно, с селективностью 84% при кортком контакте и при 80°C.
    Notizen: Abstract The title reactions were studied with a solid superacid, which was prepared by exposing Zr(OH)4 to 1 N H2SO4, followed by calcination at 650°C in air. Pentane and isopentane were converted into isopentane and isobutane, respectively, the selectivities being 84% under short contact conditions at 80°C.

    Reactions of butane and isobutane to CO and CO2 catalyzed by iron oxide treated with sulfate ion (1981)

    Beschreibung / Inhaltsverzeichnis: Abstract Катализаторы, полученные обработкой Fe(OH)3 и Fe2O3 раствором 0,5 Н H2SO4 перед кристаллизацией и дальнейшим обжигом на воздухе при 500 °C оказались высоко активными к окислению бутана и изобутана до CO и CO2, ниже 300 °C, в то время как окислы железа, приготовленные без сульфатной обработки, оказались совсем неактивными.
    Notizen: Abstract Catalysts which were obtained by exposing Fe(OH)3 and Fe2O3 prior to the crystallization to 0.5 N H2SO4 and then calcining in air at 500 °C were highly active for oxidations of butane and isobutane to CO and CO2 below 300 °C, while iron oxides prepared without the sulfate treatment were completely inactive.

    Beschreibung / Inhaltsverzeichnis: Abstract Четвертая твердая суперкислота, следующая за суперкислотами Fe2O3, TiO2 и ZrO2, была синтезирована добавлением иона сульфата к HfO2. Катализатор, полученный обработкой Hf(OH)4, приготовленного гидролизом HfCl4, 2N H2SO4 с дальнейшим обжигом на воздухе при 600–800 °C, оказался активным в скелетной изомеризации бутана до изобутана.
    Notizen: Abstract The fourth solid superacid following Fe2O3, TiO2 and ZrO2 was synthesized by the addition of sulfate ion to HfO2. The catalyst, which was obtained by exposing Hf(OH)4, prepared by the hydrolysis of HfCl4, to 2N H2SO4 and then calcining in air at 600–800 °C, was active for the skeletal isomerization of butane to isobutane.

    Preparation of superacid of ruthenium-sulfated zirconia for reaction of butane to isobutane (1999)
    Springer
    Reaction kinetics and catalysis letters 66 (1999), S. 331-336 
    Details
    ISSN: 1588-2837
    Schlagwort(e): Ruthenium-sulfated zirconia ; butane ; catalyst preparation
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Abstract A highly active superacid of 2–4 wt.% Ru-sulfated ZrO2 for the isomerization of butane to isobutane was obtained by exposing RuOx/ZrO2 to 1 N H2SO4 followed by calcining in air at 550°C. The RuOx/ZrO2 was prepared by impregnating zirconium hydroxide with a solution of RuCl3 followed by drying at 300°C. The catalyst was much more active than the superacid of sulfated zirconia, the temperature difference to show the same conversion between both catalysts being more than 145°C.
