摘要

合成了6种咪唑型离子液体[C3—8mim]Br/FeCl3

采用红外光谱和拉曼光谱对其进行表征

并考察了离子液体对二苯并噻吩的萃取脱除效果。结果发现

[C3mim]Br/FeCl3的萃取脱硫效果最佳

升高温度和增大剂油比均有利于脱硫率的提高

剂油比1:1(体积比)时

萃取时间达到12 min就可使脱硫率高达92%。且萃取反应完成后

离子液体不做处理继续重复使用

重复使用5次

脱硫率可以达到60%。

Abstract

Six sorts of [C3—8mim]Br/FeCl3 ionic liquids were synthesized

and characterized with FT-IR and Raman spectroscopy.The extraction performance of ionic liquids during the removal of dibenzothiophene(DBT)was investigated.The extraction of DBT with [C3mim]Br/FeCl3 was the best. An increase of volume ratio of ionic liquid to oil and a higher temperature benefited the desulfurization performance.The removal ratio of DBT was up to 92% in 12 min and with volume ratio of ionic liquid to oil 1:1.Reacted ionic liquid without treatment was used again for 5 times

and the removal ratio of DBT decreased gradually to 60%.
