General description
Molecular sieves are crystalline, synthetic zeolites. Their crystal gratings are similar to a cage with numerous hollow spaces. The cavities are accessible from all sides by pores of exactly defined dimensions.
Application
Molecular sieves can be used:
- in desiccators and drying tubes
- for keeping absolute solvents dry
- for drying gases or solvents in drying columns
- for selective adsorption
Features and Benefits
- Easy to use: practically chemically inert, non-toxic, no disposal problems, dried liquids can be decanted
- High adsorption capacity even with a low water content of the substance to be dried
- High adsorption capacity even at high temperatures
- High adsorption affinity for polar and unsaturated organic molecules (however, H2O is always preferentially adsorbed)
- Selective adsorption: only molecules that can pass through the pores are adsorbed
