CAS 69912-79-4: Molekularsiebe 5A

Beschreibung:
Molekularsiebe 5A sind eine Art synthetischer Zeolith, speziell ein kristallines Aluminosilikat mit einer Porengröße von etwa 5 Angström. Dieses Material zeichnet sich durch seine Fähigkeit aus, Moleküle selektiv basierend auf Größe und Polarität zu adsorbieren, was es effektiv macht, kleine Moleküle von größeren zu trennen. Die Bezeichnung "5A" zeigt an, dass es effektiv Moleküle mit einem kinetischen Durchmesser von bis zu 5 Angström adsorbieren kann, wie Wasser, Kohlendioxid und bestimmte Kohlenwasserstoffe, während größere Moleküle ausgeschlossen werden. Molekularsiebe 5A werden häufig in verschiedenen Anwendungen eingesetzt, einschließlich Gasentwässerung, Lufttrennung und Reinigung von Lösungsmitteln. Sie weisen eine hohe thermische Stabilität und Widerstandsfähigkeit gegen chemische Zersetzung auf, was ihre Nützlichkeit in industriellen Prozessen erhöht. Darüber hinaus können diese Siebe durch Erhitzen oder Spülen mit inerten Gasen regeneriert werden, was eine wiederholte Nutzung ermöglicht. Ihre hohe Oberfläche und die gleichmäßige Porenstruktur tragen zu ihrer Effizienz in Adsorptionsprozessen bei, was sie sowohl in Labor- als auch in Industrieumgebungen wertvoll macht.
