    摘要: The invention relates to heterogeneous catalysts which are particularly easy to produce. Said heterogeneous catalysts are generated by immobilizing preformed monometallic or multimetallic metal oxide particles in situ on an oxidic or non-oxidic carrier, wherefore metal oxide colloids which are stabilized by hydroxide ions and immobilized on carriers contained in the suspension are generated from conventional, water-soluble metal salts by means of hydrolysis and condensation. The inventive method makes it possible to produce fuel cell catalysts, for example.

    摘要: A process for anionic polymerization of acrylic and/or methacrylic acid derivatives or their ammonium salts with easily produced initiators. Specifically, the initiators are ammonium salts of resonance-stabilized nitrogen anions. The introduction of such initiators provides a maximum amount of structural variation, while inducing the controlled anionic polymerization of monomers at room temperature. The anionic polymerization is also applicable to acrylonitrile or methacrylonitrile or their derivatives. The polymerization process of the present invention provides polymers with definite molecular weight and limited molecular weight distribution.

    摘要: The present invention relates to a method for determining the enantioselectivity of kinetic resolution processes and of asymmetrically proceeding reactions of prochiral compounds bearing enantiotopic groups by using isotope-labeled substrates so that the reaction products can be quantitatively determined with an isotope-specific detection system, e.g., an ESI mass spectrometer. In connection with automated sample charging, the method can be employed for high throughput screening. The relevant enantioselective conversions can be induced by chiral homogeneous or heterogeneous catalysts, biocatalysts or stoichiometric amounts of optically active agents.
