AbstractVorgestellt wird die Totaloxidation flüchtiger organischer Komponenten in Gegenwart von innovativen Katalysatoren in der Gasphase. Diese bestehen aus Nickelschaum mit einer γ‐Al2O3‐Basisschicht, als Aktivkomponente wird zum einen ein silberhaltiger Perowskit, zum anderen Platin verwendet. Beide Katalysatoren zeigen hohe Aktivität bei relativ niedrigen Reaktionstemperaturen bis zu 300 °C. Die Modelledukte werden nahezu quantitativ umgesetzt.

The separation of selected 1-alkyl- and 1-aryl-3-methylimidazolium-based room temperature ionic liquid cations has been performed using reversed-phase high-performance liquid chromatography with electrospray ionization mass detection. The RP-HPLC method development started with the selection of a column taking into account especially the resolution of low molecular congeners of the selected group. Mobile phase composition was optimized for peak resolution, sensitivity and high reproducibility of retention values. The results of the method development were applied to the determination of exemplary ionic liquid species present in the medium used in cytotoxicity studies.

For ionic liquids only few toxicological and/or ecotoxicological data are available until now. A strategy is presented which aims at an environmental risk assessment of chemicals, using a combination of structure–activity relationships (SAR), toxicological and ecotoxicological tests and modelling. The parts “test-kit-concept” and “multidimensional risk analysis” are described in detail by means of selected imidazolium ionic liquids. The iterative process of this strategy offers a tool for sustainable product design.
