Volumetric Properties of Binary Mixtures Containing Chiral Ionic Liquids with a (−)-Menthol Substituent with Acetonitrile at 298.15 K.

Popis výsledku v původním jazyce

The intermolecular interactions and the influence of alkyl chain length have been investigated for three binary systems of 3-alkyl-1-[(1R,2S,5R)-(-)-menthoxymethyl]imidazolium bis(trifluoromethylsulfonyl)imide ionic liquid (alkyl = butyl, octyl, and dodecyl) with acetonitrile at 298.15 K by means of density measurements over the entire composition range. From the experimental values, the excess molar volumes and partial molar volumes were calculated and subsequently fitted using the Redlich-Kister equation. We have found that the excess molar volumes were negative for all three systems corresponding to a better arrangement of the molecules and/or stronger interactions. The parameters of the Redlich-Kister equation were optimized by means of a robust regression along a gnostic influence function. This made possible a deeper analysis of the experimental data. Partial molar volumes and excess molar volumes at infinite dilution using these parameters could then be calculated, allowing for a sound estimate of the solute-solvent interaction between the studied ionic liquids and acetonitrile.
