protic ionic liquids (PILs), it has been concluded that not all PILs exist as molecular aggregates in the gas phase. The detection of both ions of m/z 115.0 and m/z 116.0 for the 1,1,3,3-tetramethylguanidinium trifluoromethylsulfonate (TMGS) protic ionic liquid indicates that both the molecular and ionic aggregates co-exist in the gas phase, which is to say that the TMGS may also evaporate via the ionic
根据对1,1,3,3-四甲基胍基质子离子液体(PIL)的EI-MS研究,可以得出结论,并不是所有的PIL都以分子聚集体的形式存在于气相中。对1,1,3,3-四甲基胍三氟甲基磺酸(TMGS)质子性离子液体的m / z 115.0和m / z 116.0两种离子的检测表明,分子聚集体和离子聚集体共存于气相中,就是说TMGS也可能通过离子聚集体就像非质子离子液体一样。此外,对基于三乙胺和基于1-甲基咪唑的PIL的研究证实,PIL的气相结构取决于相应酸和碱的酸度和碱性。
