以氯甲基化聚苯乙烯(CMPS)树脂为载体，采用接枝法制备了一系列聚合物负载金属氯化物咪唑离子液体(IL)基团M/CMPS-Im(Cl)(M=CuCl2、ZnCl2和FeCl3)。同时，用傅立叶变换红外光谱(FTIR)、X射线光电子能谱(XPS)和扫描电子显微镜(SEM)对合成的离子液体进行了结构表征。结果表明，CMPS树脂表面覆盖有一层较薄的萃取剂活性成分。然后，在一定条件下，考察了合成的CMPS负载咪唑基ILS对模型汽油(正辛烷/噻吩组分)中的噻吩类及其衍生物的萃取性能。对于特定的咪唑基离子，萃取剂的萃取量大小顺序为CuCl/CMPS-Im(Cl)&Gt；ZnCl2/CMPS-Im(Cl)&Gt；FeCl3/CMPS-Im(Cl)，其原因是Cu3+与噻吩类离子的π-络合能力强于Fe3+和Zn2+。二是选择性脱硫剂。
A series of polymer-supported metal chlorides imidazolium ionic liquid (IL) moieties, M/CMPS-Im(Cl) (M = CuCl, ZnCl2 and FeCl3), were synthesized by grafted method using chloromethylated polystyrene (CMPS) resin as support. Meanwhile, the structures of synthesized ILs were characterized by Fourier transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS), and scanning electron microscope (SEM). The results showed that the surface of CMPS resin was covered with a thin layer of extraction activity components. Then, the synthesized CMPS-supported imidazolium-based ILs were investigated to extract thiophene and its derivatives from model gasoline (n-octane/thiophene) under certain conditions. For a given imidazolium-based IL: first, the order of extraction capacity of extractant was CuCl/CMPS-Im(Cl) > ZnCl2/CMPS-Im(Cl) > FeCl3/CMPS-Im(Cl); the reason for this was that the π-complexation capability between Cu+ and thiophene was stronger than those of Fe3+ and Zn2+. Second, the sulfur removal selectivit...
