Type 3A Molecular Sieve

K12[(AlO2)12(SiO2)12] · X H2O--Molecular Sieve Type 3A, the potassium form of the Type A Crystal structure, is an alkali metal alumino-silicate. Available in powder and pellets for commercial dehydration of unsaturated hydrocarbon streams such as cracked gas, propylene, butadiene and acetylene. Type 3A is also used for drying polar liquids such as methanol and ethanol.
