General description

Molecular sieve 0.4 nm is a porous solid that can be used in desiccators and drying tubes to dry gases and absolute solvents. It also changes its color from brown to yellowish at a water uptake of approximately 7-10 g/100 g molecular sieve.

Application

Molecular sieve 0.4 nm can be used as a catalyst:
  • For the conversion of epoxides to thiiranes by treating with thiourea.
  • In the solvent-free acetylation of eugenol with acetic anhydride to synthesize eugenyl acetate.
It can also be used as catalyst support in the copper-palladium bimetallic catalyzed Suzuki-Miyaura coupling of aryl halides with phenylboronic acids to synthesize biphenyls.

Features and Benefits

  • Easy to use
  • Chemically inert
  • Non-toxic
  • Dried liquids can be decanted
  • High adsorption capacity
  • Selective adsorption
  • Reusable
