| 英文摘要: | For the first time, we reported the preparation of the oligomer of carbon dioxide. The oligomerization of carbon dioxide was carried out with the aid of the synergetic catalysis of 1,8-diazabicyclo(5, 4, 0)undec-7-ene (DBU) and quaternary salt of water-soluble chitosan (QWSC), which was conducted at 75 °C for 24 h by using petroleum ether as dispersing medium. The product was separated and purified through repeated dissolution-precipitation by using dichloromethane, petroleum ether and distilled water as solvents and precipitant respectively. Fourier transform infrared spectroscopy (FTIR), fluorescence spectroscopy, carbon nuclear magnetic resonance (13CNMR), and MALDI-TOF spectrometry (MS) was applied to characterize the product. The results confirmed that the obtained product was the expected oligomer of CO2, linear H-(O-CO)17-H and cyclic (O-CO)13 containing DBU-like group. © 2018 Elsevier Ltd. All rights reserved. |
