Abstract
Description
Polymeres Siliciumdioxid in Form von Kieselgelen, Kieselsolen und gefällten oder pyrogenen Silicium dioxid findet zahlreiche Anwendungsgebiete in der Verfahrenstechnik, der chemischen Technologie und Pharmazie.Polymeric silica in the form of silica gels, Silica sols and precipitated or pyrogenic silicon Dioxide finds numerous areas of application in process engineering, chemical technology and pharmacy.
Bedingt durch die hohe Absorptionsfähigkeit, die große Oberfläche und chemische Stabilität wird Siliciumdioxid als Katalysatorträger, zum Reinigen oder Trennen von Flüssigkeiten und Gasen, zum Binden chemischer Substanzen, zum Trocknen von Gasen oder Flüssigkeiten sowie als Träger von Arzneistoffen verwendet.Due to the high absorbency, the large surface area and chemical stability Silicon dioxide as a catalyst carrier, for cleaning or separating liquids and gases, for Binding chemical substances, for drying Gases or liquids and as a carrier of Drugs used.
Eine magnetische Beeinflussung im Sinne eines Ein- oder Austrages, Steuerung, Positionierung oder separieren von polymerem Siliciumdioxid würde die Anwendung und Handhabung verfahrenstechnischer, chemischer, analytischer oder pharmazeutischer Vorgänge verbessern oder erst ermöglichen.A magnetic influence in the sense of a Entry or exit, control, positioning or would separate polymeric silica the application and handling of process engineering, chemical, analytical or pharmaceutical Improve processes or enable them first.
Erfindungsgemäß wird deshalb vorgeschlagen, in die Matrix polymerer Siliciumdioxidverbindungen magnetische Materialen einzubinden.According to the invention it is therefore proposed in the matrix of polymeric silicon dioxide compounds to incorporate magnetic materials.
Fällungskieselsäuren und Kieselgele, denen hinsicht lich des Produktionsumfanges die größte Bedeutung zukommt, werden aus wäßrigen Alkalisilikatlösungen durch Fällung und Kondensation mit Mineralsäuren hergestellt.Precipitated silicas and silica gels, which respects most important in terms of production volume comes from aqueous alkali silicate solutions by precipitation and condensation with mineral acids produced.
Erfindungsgemäß wird vorgeschlagen, in Alkalisilikat lösungen wie z. B.
