Sonochemical synthesis of aluminum fumarate for CO2 cycloaddition to epoxides |
| 초록 |
Aluminum fumarate was tested as a catalyst for CO2 cycloaddition to epoxides under solvent-free reaction conditions. It was synthesized hydrothermally via a sonochemical route (Al fumarate-(S)), which exhibited a higher catalytic activity than Al fumarate synthesized by a conventional method (Al fumarate-(C)) because of the higher number of Lewis acid sites formed in Al fumarate-(S). The CO2 uptake of Al fumarate-(S) was higher than that of Al fumarate-(C) at 1 bar. High conversion (96%) of epichlorohydrin with excellent selectivity (97%) to cyclic carbonate was obtained at 50 °C and 10 bar CO2 after 6 h of reaction. However, the recovered Al fumarate-(S) catalyst showed a steady decrease in catalytic activity for the duration of the recycling runs. The cause of deactivation was investigated by N2 adsorption-desorption isotherms and spectroscopic analyses. |
