CAS 308080-99-1: Zeólita3A
Descrição:
A zeólita 3A é uma zeólita sintética, especificamente um tipo de aluminosilicato com uma estrutura de rede tridimensional. É caracterizada por sua capacidade de adsorver seletivamente moléculas com base no tamanho e na polaridade, tornando-a particularmente eficaz como um tamiz molecular. A designação "3A" indica que possui um tamanho de poro de aproximadamente 3 angstrons, permitindo que ela prenda seletivamente moléculas menores enquanto exclui as maiores. Essa propriedade é utilizada em várias aplicações, incluindo separação de gases, agentes desidratantes e catálise. A zeólita 3A possui uma alta área de superfície e capacidade de troca iônica, o que aumenta sua eficácia em vários processos químicos. Além disso, é estável em uma ampla gama de temperaturas e condições, tornando-a adequada para aplicações industriais. Sua fórmula química geralmente inclui íons de sódio, que podem ser trocados por outros cátions dependendo da aplicação específica. No geral, a zeólita 3A é valorizada por sua versatilidade e eficiência em adsorção e catálise tanto em ambientes laboratoriais quanto industriais.

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.Pureza:Min. 95%Cor e Forma:White/Off-White SolidMolecular sieves, 3A, powder
