Molecular sieve 4A
Molecular Sieve 4A is a synthetic crystalline aluminosilicate with a regular micropore structure.
Molecular Sieve 4A is the potassium-sodium form of the molecular sieve type A.
Chemical Formula: Na2O * Al2O3 * 2SiO2 * n H2O
Molecular Sieve 4A is a widely used adsorbent for many different applications. It displays a high-water adsorption capacity already at low partial pressures and still at temperature up to 100°C.
Molecular Sieve 4A is commonly used for drying organic liquids (solvents, oils, gasolines, and other saturated hydrocarbons), air, liquid gases (propane, butane) as well as technical and noble gases (H2, N2, He, Ar, etc.)
