| Abstract: | Using triethylenediamine as raw material,five kinds of dinucleic acid ionic liquids(ILs)with different anionic structures were synthesized by a two-step method.The structure and properties of the IL were characterized by FTIR,1H NMR,UV-vis and other techniques.Triethylenediamine ILs were further applied to the denitrification of oil products.Several variables such as ILs/H2O mass ratio,extraction temperature,extraction time,standing time and ILs/oil mass ratio on the removal of non-basic nitrogen compound indole were studied.The recycling performance of IL was also discussed.The experimental results indicate that the removal efficiency of indole byDABCO-PS]HSO4 is up to 74.0%when the reaction conditions of ILs/oil mass ratio is 1∶10,ILs/H2O mass ratio is 1∶0,extraction temperature is 40℃,extraction time is 1.0 h and standing time is 20 min.The removal efficiency has no significant decrease after the recycling of IL for 5 times.The method described hereby has the advantages of cheap raw material,simple synthesis process and good potential for industrial application. |
