Overview

5A molecular sieves have a pore size of approximately 5 angstroms. The effective pore size is 0.5–0.57 nm. It is irritating. It dissolves in strong acids or bases and decomposes, but is insoluble in water and organic solvents. It is hygroscopic. It is a selective adsorbent, catalyst, or catalyst support. Applications include the separation of n- and isoalkanes, the separation of oxygen and nitrogen, desulfurization of petroleum and petroleum gas, and the drying and purification of gases and liquids.
