Product Description
4A molecular sieve is an alkali metal aluminosilicate that can adsorb water, NH 3 , H 2 S, sulfur dioxide, carbon dioxide, C 2 H 5 OH, C 2 H 6 , C 2 H 4 Molecules with a critical diameter no greater than 4 Å. They are widely used for the drying of gases and liquids and can also be employed for the refining and purification of certain gases or liquids, such as the production of argon.
Reference parameters
Chemical formula: Na 2 O·Al 2 O 3 ·2SiO 2 ·9/2H 2 O
