chemical fixation of CO2 into polycarbonates by zinc glutarate and its derivatives |
초록 |
A heterogeneous zinc glutarate (ZnGA) catalyst and its derivatives were prepared from various zinc and glutarate sources. The ZnGA single crystals (sc-ZnGA), with a monoclinic lattice unit cell, as determined by X-ray single-crystal structural analysis. The structural details of the ZnGA catalyst are crucial in helping to elucidate its activity in the copolymerization reactions between carbon dioxide (CO2) and alkylene oxides. The activity of the ZnGA catalyst in the copolymerization of CO2 and PO was found to depend on the zinc source used, and its ability to produce a catalyst of large surface area and high crystallinity (≥77%). Modification of the glutarate ligand with electron-donating or withdrawing substituents failed to enhance the ZnGA catalyst activity further, indicating that glutarate is the best ligand for the Zn metal ion to achieve a high catalytic activity in the CO2 copolymerization with PO. |
