DESCRIPTION
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.
Features and Benefits
- Easy to use
- Chemically inert
- Non-toxic
- Dried liquids can be decanted
- High adsorption capacity
- Selective adsorption
- Reusable
