N2 - The satisfactory mutual solubility of aniline and bis(trifluoromethylsulfonyl)amide or trifluoromethanesulfonate-based ionic liquids can open new perspectives in processing of phenylamine derivatives. Liquid-liquid equilibrium (LLE) and solid-liquid equilibrium (SLE) measurements were performed using a dynamic (synthetic) method. The solubility of aniline in trifluoromethanesulfonate ionic liquids was found to be significantly lower than in the studied bis(trifluoromethylsulfonyl)amide ionic liquids. Furthermore, the solubility of aniline in mixed solvents was studied, and thus, the possibility to enhance solubility maintaining benefits coming from the presence of hydrophilic trifluoromethanesulfonate ionic liquid was highlighted.
