    Inventors: Peter Birke, Reinhard Geyer, Peter Kraak, Rainer Schodel
  • Patent number: 5736479
    Abstract: The invention concerns new oxidation catalysts, methods of producing them and their use. These catalysts consist of titanium silicalites crystallized in situ onto activated charcoal or metal oxides. The titanium silicalite content lies preferably in the range of 30 to 60% by wt. The atomic ratio of Si to Ti in the carrier-borne phase is 10 to 100. Such catalysts are particularly suitable for oxidation reactions with H.sub.2 O.sub.2 under mild conditions, such as temperatures of 20.degree. to 120.degree. C. and pressures equal to or higher than atmospheric.
    Type: Grant

  • Patent number: 5178846
    Abstract: An economical and environmentally safe method for synthesizing wide-pore aluminophosphate crystalline molecular sieves primarily involves inorganic synthesis requiring no structure-directing organic templates. In addition to aluminium and phosphate, further components selected from group IV of the periodic table of elements can be added to synthesize multi-component phosphate molecular sieves such as germano-silico-alumino-phosphate crystalline structures.
