  Three novel alkoxyl-functionalized ionic liquids (ILs), 1-(3-triethoxysiyl propyl)-3-methyl imidazolium tetrafluoroborate (TESPMIM[BF4]), 1-(3-triethoxysiyl propyl)-3-methyl imidazolium hexafluorophosphate (TESPMIM[PF6]) and 1-(3-triethoxysiyl propyl)-3-methyl imidazolium bis(trifluoromethanesulfony)imide (TESPMIM[N(SO2CF3)2]) were synthesized and used as selective coating materials to prepare chemically bonded IL-based organic-inorganic hybrid solid phase microextraction (SPME) fibers by sol-gel technology.The possible mechanism of the sol-gel process was proposed, and the successful binding of ILs to the sol-gel substrate was confirmed by FT-IR spectroscopy.

乙二醇是一种重要的有机化工原料,主要用于生产聚酯、汽车用冷冻剂等产品。紫外透光率(简称UV值)是衡量聚酯级乙二醇产品质量的一项重要指标。乙二醇UV值不合格,将影响下游产品聚酯的质量,如光泽和色度。研究影响乙二醇UV值的杂质(UV物)的结构及其成因,对于改进乙二醇生产工艺、提高产品质量具有积极的意义。由于影响乙二醇紫外透光率的杂质含量极低,使用气质联用技术或液相色谱手段难以直接进行结构鉴定。本文采用
