A 1-alkylcyanopyridinium-based ionic liquid in the separation processes

The activity coefficients at infinite dilution, γ13∞ for 65 solutes, including wide spectra of alkanes, alkenes and alkynes as well as aromatic hydrocarbons, alcohols, water, ethers, ketones, acetonitrile, pyridine, 1-nitropropane, thiophene, and esters in the 1-butyl-4-cyanopyridinium bis{(trifluoromethyl)sulfonyl}imide [BCN4Py][NTf2] were determined by gas–liquid chromatography for all solutes at seven temperatures in range of (308.15 to...
