Separation of water/butan-1-ol mixtures based on limiting activity coefficients with phosphonium-based ionic liquid

In the present work the limiting activity coefficients (γ13∞) for 64 solutes, including polar and non-polar solutes as alkanes, alkenes and alkynes as well as aromatic hydrocarbons, alcohols, water, ethers, ketones, acetonitrile, pyridine, 1-nitropropane, thiophene, and esters in the tributyltetradecylphosphonium dodecylbenzenesulfonate, [P14,4,4,4][DBS] were determined by gas-liquid chromatography at six temperatures in range of (318.15–368.15)...
