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

Analysis Note

Identity: conforms
Loss on ignition (950 °C): ≤ 10 %
Water absorption capacity (24 hrs.,80 % relative humidity): ≥ 15 %
