CAS 308080-99-1: Zéolite3A
Description :
La zéolite 3A est une zéolite synthétique, spécifiquement un type d'aluminosilicate avec une structure de cadre tridimensionnelle. Elle se caractérise par sa capacité à adsorber sélectivement des molécules en fonction de leur taille et de leur polarité, ce qui la rend particulièrement efficace en tant que tamis moléculaire. La désignation "3A" indique qu'elle a une taille de pore d'environ 3 angströms, lui permettant de piéger sélectivement des molécules plus petites tout en excluant les plus grandes. Cette propriété est utilisée dans diverses applications, y compris la séparation des gaz, les agents de séchage et la catalyse. La zéolite 3A a une grande surface spécifique et une capacité d'échange ionique, ce qui améliore son efficacité dans divers processus chimiques. De plus, elle est stable dans une large gamme de températures et de conditions, ce qui la rend adaptée aux applications industrielles. Sa formule chimique inclut généralement des ions sodium, qui peuvent être échangés avec d'autres cations selon l'application spécifique. Dans l'ensemble, la zéolite 3A est appréciée pour sa polyvalence et son efficacité en adsorption et en catalyse tant dans les environnements de laboratoire qu'industriels.

CAS :Zeolite 3A is a porous mineral that has a structure of small cavities, or pores. It is used as an adsorbent to remove toxic chemicals and heavy metals from water. Zeolite 3A can be activated by heating at high temperatures in the presence of air, which creates larger pores on the surface and increases its adsorption capacity. Zeolite 3A has been shown to have a Langmuir adsorption isotherm with a maximum adsorption capacity of 10-20%. The hydroxyl groups on zeolites are known to form hydrogen bonding interactions with water vapor molecules, which may account for its ability to remove water vapor from the atmosphere. Zeolite 3A also has been shown to be an effective catalyst for oxidation reactions due to its strong chemical stability.Degré de pureté :Min. 95%Couleur et forme :White/Off-White SolidMolecular sieves, 3A, powder
