• 論文の詳細を見る

• Synthetic zeolites were found to be effective catalysts for the synthesis of 1-substituted 2-pyrrolidinone by the reaction of γ-butyrolactone with amines. 1-Propyl-2-pyrrolidinone was obtained in the equilibrium yield with practically 100% selectivity over copper exchanged Y-zeolite at 280 °C. The effects of reaction temperature, contact time and partial pressures of the reactants were examined. A reaction mechanism is proposed for the ring transformation based on the kinetic studies of the reaction of γ-butyrolactone with propylamine.
