Molecular sieve a 4 or molecular sieve 4 angstrom (zeolite a 4); Molecular sieves are materials with a three-dimensional structure of aluminosilicates that have a porous network with regular holes of the same size. Due to their micro pore structure, zeolites can selectively absorb and separate different materials. Molecular reservoirs are classified based on the size of their holes and have holes with a size of 3 to 10 angstroms .

Molecular sieve a 4 is obtained from ion exchange with potassium and sodium, and the holes of these materials have a size of about 4 angstroms, and based on this, molecules with a molecular diameter of less than 4 angstroms (including water) are absorbed by these materials, and molecules with A diameter larger than this value will not be able to enter the absorbent holes. A4 molecular resins are widely used in dehumidification from different streams in different industries .

What is the difference between the molecular ratios of a 3 and a 4?

Molecular reaction a 4 has a slightly larger pore size of approximately 4 angstroms. This difference in pore size affects their ability to absorb different types of molecules. In general, molecular ratio a 3 is more suitable for dehumidification and removal of small polar molecules such as water, while molecular ratio a 4 is more suitable for removing larger polar molecules such as ethanol and methanol in addition to removing water .
