Synthesis of Glycidamide from Acrylonitrile Using Basic Hydrotalcite Catalyst in the Presence of Aqueous Hydrogen Peroxide and Unsaturated Amide

摘要

Glycidamide (GA) can be synthesized from acrylonitrile (AN) by using hydrotalcite as a solid base catalyst and 25% aqueous H2O2 as an oxidant, in the presence of acrylamide (AA) as a cocatalyst in methanol solvent at 313 K for 18 h. The GA yield and H2O2 utilization efficiency reached 74% and 60%, respectively. The hydrotalcite catalyst could be easily separated from the reaction mixture and reused at least once.
