Gas-Phase Synthesis of Dimethyl Carbonate from Methanol and Carbon Dioxide Over Co1.5pw12o40 Keggin-Type Heteropolyanion
The reactivity of Co(1.5)PW(12)O(40) in the direct synthesis of dimethyl carbonate (DMC) from CO(2) and CH(3)OH was investigated. The synthesized catalyst has been characterized by means of FTIR, XRD, TG, and DTA and tested in gas phase under atmospheric pressure. The effects of the reaction temperature, time on stream, and methanol weight hourly space velocity (MWHSV) on the conversion and DMC...
متن کاملSynthesis of carbamates from aliphatic amines and dimethyl carbonate catalyzed by acid functional ionic liquids
Selective synthesis of carbamates from amines and dimethyl carbonate were studied in the presence of various ionic liquids as catalysts. The SO3H-functionalized ionic liquid was found to be the most active catalyst among the applied ionic liquids, and nearly 100% conversion and 95% electivity were achieved when using 1,6-hexanediamine as reactant. The acid functional ionic liquid catalyst syste...

In the crystal structure of the title compound, C(5)H(8)N(4), adjacent mol-ecules are connected through N-H⋯N hydrogen bonds, resulting in a zigzag chain along [100]. The amino groups and heterocyclic N atoms are involved in further N-H⋯N hydrogen bonds, forming R(2) (2)(8) motifs.
