Merck, MX1583D-1, Molecular Sieve, Type 3A

General description
Molecular Sieve, Type 3A is a synthetic crystalline aluminosilicate (potassium form crystal structure or type A zeolite) with an effective pore diameter of 3 Å. It is used as an effective adsorbent. It adsorbs molecules having a kinetic diameter of less than 3 Å and excludes molecules with a kinetic diameter of greater than 3 Å.
Application
Molecular Sieve, Type 3A can be used:
As a selective adsorbent for the adsorption of water and ammonia.
In drying polar liquids such as methanol and ethanol.
In commercial dehydration of unsaturated hydrocarbon streams, including cracked gas, propylene, butene, and natural gas.
