Resumo(s)
This Thesis is mainly focused on phase behaviour in macro and nano domains and
thermodynamic properties of mixtures containing ionic liquids and water, fluorinated or organic solvents.
A broad list of commercially available ionic liquids or specific and functionalised, synthesised and
characterised by the author of the Thesis is included in this study. The used ionic liquids contained the
following cations: 1-alkyl-3-methylimidazolium [Cnmim]+, 1-alkyl-3-methylpyridinium [Cnmpyr]+, 1-
alkyl-1-methylpyrrolidinium [Cnmpyrr]+, 1-alkyl-1-methylpiperidinium [Cnmpip]+, and
tetraalkylphosphonium [CxCyCzCwP]+ and some of the anions: chloride Cl-, Br-, hexafluorophosphate
[PF6]-, bis{(trifluoromethyl)sulfonyl}amide [NTf2]-, alkylsulfonate [CmSO3]-, trifluoromethanesulfonate
[OTf]-, dicyanamide [dca]- and acetate [Ac]-.(...)
