Surface Tensions of Ionic Liquids: Non-Regular Trend Along the Number of Cyano Groups.

ABSTRACT: Ionic liquids (ILs) with cyano-functionalized anions are a set of fluids that are still poorly characterized despite their remarkably low viscosities and potential applications. Aiming at providing a comprehensive study on the influence of the number of -CN groups through the surface tension and surface organization of ILs, the surface tensions of imidazolium-based ILs with cyano-functionalized anions were determined at atmospheric pressure and in the (298.15 to 343.15) K temperature range. The ILs investigated are based on 1-alkyl-3-methylimidazolium cations (alkyl = ethyl, butyl and hexyl) combined with the [SCN]^-, [N(CN)₂]^-, [C(CN)₃]^- and [B(CN)₄]^-anions. Although the well-known trend regarding the surface tens
