Polar molecules (such as water) and unsaturated molecules
Molecular sieve is an aluminosilicate compound with a cubic lattice. Molecular sieve has a uniform microporous structure, and its pores have uniform diameters. These pores can adsorb molecules smaller than their diameter into the interior of the pore cavity, and have preferential adsorption capacity for polar molecules and unsaturated molecules. Therefore, they can separate molecules with different degrees of polarity, different degrees of saturation, different molecular sizes and different boiling points.
