文摘

The hydrogen bonding interaction between acetate-based ionic liquids (AcILs) 1-ethyl-3-methylimidazolium acetate [EMIM][Ac] and seven solvents (deuterated water D₂O, deuterated methanol CD₃OD, deuterated acetonitrile CD₃CN, deuterated dimethylsulfoxide d₆-DMSO, deuterated acetone CD₃COCD₃, deuterated benzene C₆D₆, and deuterated chloroform CDCl₃) was investigated in their whole concentrations by ATR-IR and ¹H NMR. Results show that both [EMIM][Ac] and solvent chemical shifts 未 present a different change in the ¹H NMR in different solvents. ATR-IR wavenumber shifts 谓 of [EMIM][Ac] and solvents also present corresponding variation tendency.
