    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.
    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
