Product Name:Molecular Sieve
English Name:Molecular Sieve
CAS No.:12173-28-3
Aliases:Molecular Sieve 5A, 5A Molecular Sieve, Zeolite 5A
Molecular Formula:Ca₄Na₄(Al₁₂Si₁₂O₄₈)·xH₂O
Physical Properties:White or light gray powder, odorless and tasteless. Melting point above 600°C with good thermal stability. Insoluble in water and organic solvents; forms a reversible hydrate in water (hydrolysis sensitivity class 5) with excellent adsorption performance. Effective pore size approximately 5Å (0.5nm), capable of adsorbing molecules smaller than this diameter. Bulk density approximately 0.7g/mL, specific surface area 500-800m²/g.
Uses:Primarily used as a high-efficiency desiccant for drying natural gas, cracked gas, refrigerants, and various organic solvents. Widely applied in air separation and gas purification to effectively remove carbon dioxide, sulfides, moisture, and other impurities. Also serves as a catalyst support, ion exchanger, and chromatographic stationary phase.
Technical Specifications:
Purity ≥99%
Effective pore size approximately 5Å
Melting point >600°C
Bulk density approximately 0.7g/mL
Static water adsorption capacity ≥20% (25°C, RH 60%)
